Help i cant play my A game in badminton?

It's hard in any sport to truly be on your A game as it's called. Some people are simply able to get into a rythym faster and more than others. Part of playing well is having the pion and drive to do so. Do you enjoy playing badminton? Do you feel that you have to prove yourself? Is the game fun while playing? A no answer to any of these can cause you to lose focus during the game. I'm not an expert at badminton and hardly play it, so I don't know exactly what it takes to get into the game.
