I'm not sure if anyone has mentioned this kind of problem before, but... When talking about psychological problems while playing badminton, it usually leans toward a lack of confidence when playing against superior players, or a lack of motivation, etc. Some of my friends and I, though, are kind of the opposite. Whenever we play against someone we are familiar with, like someone on the team (I play high school badminton), or against someone that is below our level, we tend to get bored and play in a very mediocre fashion. Well, maybe getting bored isn't the right word. For me, if I want to play my best, I almost absolutely must have that rush of adrenaline/excitement when playing. Otherwise, I can't focus or concentrate, and will even completely miss the shuttle on many of my swings. Playing against someone that I'm familiar with or someone who is at a lower lever doesn't provide that same thrill, and I always wind up playing horribly against them. The latter part isn't too much of a problem, because if they really ARE at a lower level than myself, I can probably beat them regardless. The only problem is, whenever I challenge a teammate to rise up in rank, I always do much worse than normal, because of the problem outlined above. Does anybody have any idea of how to solve this? I'd really appreciate your help!
