Getting to the next level, whether 3.0, 3.5, or higher, isn't easy. The answer is practice, of course, but just getting out to the court every day isn't enough. You must practice with a goal in mind, and you must know HOW to practice to achieve that goal. One "simple" way to get better is to concentrate on the skills that are missing from the level above your current level (based on these criteria as noted by the USAPA). ​
Let's say You haven't been playing pickleball that long and you want to get to be a 4.5 player. What do you need to do? What are the major differences between 3.0 and 4.5?
The table below (info from the USAPA website) lists these definitions:

I highlighted two items in the table that popped out at me: CONSISTENCY and STRATEGY. Other elements are important, of course, but by the time a player has achieved 3.0-level skills, he or she knows how to do a lot of things—just not how to do them well, or consistently. What that player doesn't really know yet is the strategy that goes along with what is known: when to hit a dink instead of a drive, when to break out of dinking, and so on. That's the strategy bit, and learning is not all—it's also being able to know how to do it automatically and not have to think about it.

If you've read my posts before, you know I stress PRACTICE, and not just aimless hitting back and forth over the net. It's important to have a goal—one that's reachable and measured. Like consistently hitting that forehand that sometimes goes out of bounds or into the net.

Get a friend to work with you (or better yet, take classes) and make sure 1) you're doing the stroke correctly before you continue to learn it wrong; 2) concentrate your focus not on everything about that shot but rather small parts of it: hitting it at about the same height and to roughly the same spot on the court.

Once you have mastered that, move the shot to other areas. When that's easy, work on your backhand and do the same thing. All of this takes time, but if you do this practice consistently (couldn't resist putting that in), your game will improve.

Take things slowly and methodically, knowing it took a while to get from novice to 3.0. With patience and some help from your friends, you'll get there.

Most of you who consistently try to get better at pickleball can probably remember a day (hopefully many) when you had an "AHA!" moment—when something clicked, made sense, or felt right for the first time. Armed with this new insight or technique, your game improved. You knew you finally had it—you'd figured it out. Then, when you’re weren't looking, that new technique or knowledge disappeared or devolved into an old pattern.

When you first "get it," you feel excited about the new technique. Perhaps you found out what you've been doing wrong with your backhand, or someone pointed out that you need to wait longer before hitting the ball. You managed to keep these things in mind for a while, but soon you were back to your old ways.

Sometimes, we really do turn over a new leaf and it grows into a tree (poor metaphor, but hey). More often we return to old patterns without ever meaning to. So when they do stick, and what makes the difference?

The Missing Element

We don’t have a hope of keeping a new technique unless we use it in regular practice. The old conditioning of your muscles and your mind is too strong for your mindful desire to change to be enough. You must condition that new technique until your muscles and mind don't remember the old way.

You Need to Practice

Just a short amount of mindful practice of your new technique every day is enough to get a foothold and start to dissolve the reflexive nature of the old behavior. It isn't a good idea to focus on more than one thing at a time. Give your mind and body a chance to engrain the new pattern before working on something else.

It might be as easy as taking five minutes out of your morning couples game to have your partner reinforce the new pattern, either by hitting balls to you or watching to make sure you're returning them correctly. No doubt your friends could use practice, too, so you'll all benefit.

Doing even a little bit of the new technique routinely starts to break down the automatic nature of doing the old one. The new way happens without thinking about it more often. Gradually, the new way becomes natural.

The "AHA!" moment is only the first step on the road to improving your game. You really change when this new way of playing feels natural, and for that to happen, you need to practice.

​This afternoon, I received an email from an 82-year-old gentleman who said he'd read and enjoyed The Art of Pickleball. He said he hoped I had some tips regarding playing singles—his game of choice—as he'll be playing in a tournament soon. After applauding him for playing singles at his age, I scoured my notes, watched some videos by YouTube pros, and collected these tips. I hope they're useful to you when you are 82!

Tips for Better Singles Play

• Stay close to the center line when you serve, so you can reach the returned shot with fewer steps. Face your opponent and watch his paddle angle and the ball, so you'll know where it's headed.
• Singles pickleball is a lot like singles tennis, in that you should keep your feet moving. Don't get caught flat-footed, and you'll be able to get to the shots more easily.
• I watched a Kyle Yates video where he said his technique in singles was to hit mostly forehands (that's always good advice) and long drives as hard as he could. I don't think that will work for everyone, but it won him the gold. Deep, hard serves are more difficult to return and may help you on your way to the non-volley zone, if your opponent's return is weak. Same for the return of service—send it deep and hard, and hopefully you can gain the net or at least try for a good passing shot. 
• Regarding hitting forehand: many singles players seem to win by having that good footwork and the agility to "run around" their backhand, allowing them to hit forehand instead. Yet I heard one retired tennis coach take umbrage with that, insisting players should work on their backhands, as that was ultimately a lot easier. It's true that you usually hit harder with a forehand stroke, so when power is called for, stick to forehand when possible.
• When you're in the back court, hit deep to the corners, not down the middle—just opposite of typical doubles strategy. Keep your opponent running side to side, which he should find the most difficult. 
• Try not to get stuck in mid court, where your opponent can send shots to your feet. If you can't get to the net, stay in the back third of the court until you can, or hit a split step if you get caught, grounding yourself for a good return, and then hustle toward the net again. 
• Get to the non-volley zone, just as in doubles. That's where your power is. From there, volley your opponent's returns and, again, hit toward the corners to keep him moving and ultimately to put away the shot. You can use a hard drive, if he's in the back court, or a drop volley to get to the net (add underspin/backspin to the ball to make it tougher for him to return it). Don't use a drop shot if your opponent is deep—you want to keep him away from the net. Keep pounding him with long drives to the back court.
• If your opponent does get to the net, you can force him back with a lob (not commonly done anymore, because many players often smash it back for a put-away) or hit a passing shot. Which you use depends on your skill and your opponent's skill. 
• Stay on the attack. Send shots to your opponent's backhand, as it's typically weaker.

Drills for Singles Play
This man also asked if I could suggest drills for singles. Here they are:

• Hit serves and returns so they land within two to three feet of the baseline. If practicing with a partner, send shots to your partner's backhand. Have your partner do the same for you.
• Practice drop volleys from the baseline, sending them to the sides rather than the center of the non-volley zone. 
• Have a partner send shots to you at the baseline, aiming for the corners. Concentrate on your footwork and staying mobile between the shots.
• All target practice drills are good. 

Some fans of The Art of Pickleball have asked me to publish a book cataloguing the many kinds of pickleball drills. I don’t have current plans to do that, but in the meantime, I’ll share this much.

While practice of any kind will help you reach a higher level, like it or not, drills are particularly helpful because:
1)  They provide good practice without the pressure of a game, and
2)   Whatever your level, you’ll get more practice in the same amount of time when concentrating on just one thing at a time.

Some players have a weekly regimen of drills they do to keep them on top of their game. Some work strictly on elements that need improvement. Some split their time doing both.

I believe drills are best used to focus on what you do poorly to make that your strength. Maybe you always miss your drop shot, or lobs always go long. You know what your problem areas are—but you probably don’t know what you’re doing incorrectly that causes the problems or what to do to fix them. (If you did, you wouldn’t still be making the error!)
