I cite myself as a perfect example. When I was first learning pickleball, I searched for a book that would tell me how to play better. I also asked good players how they did what they did. Later, as I began compiling material for The Art of Pickleball, I realized that, while some techniques were suggested more often than others, there was still a fair amount of difference of opinion among the "experts."
Making it more confusing is that new methods appear as the game evolves. Take the ready position, for example. For years, it was accepted that you should stand facing the net with your knees bent and your paddle in front of you aimed at the 12-o'clock position (as viewed from above). Recently, an alternative method emerged at the net, where the paddle is held in the backhand position, ready to volley the ball back over the net. Now that's being refuted. Which method is best?
Remember, too, that no two bodies are alike. The person suggesting you hold your paddle at a certain angle might be quicker than you in moving from one position to another. What works for her might be terrible in your hand.
My advice is to check out different ways of doing things and settle (for now) on what seems best to you. When a new method comes along, embrace it if it's better. Just remember: there's no one right way to do anything in pickleball, or in life.
