Many players try to imitate better players too much. While copying what the top players do is usually good, some players end up doing things that just don't come naturally for them.
I have fallen into this trap at times. The key to getting better and continuing to enjoy the sport is to imitate some things, but to truly try to find a game that matches your personality, physical ability and table tennis talents.
For example, if you are a patient person, perhaps a consistent medium-speed looping game is what you would be best at.
If you are more aggressive, perhaps you should work on developing a great backhand or forehand kill. The idea is to truly imagine what you want to be and then try to figure out how to get there.
If you have good touch, but are a little slow, continue to develop your footwork, but realize that your backhand and touch are going to be what wins for you, not running around to play forehand and invariably getting off balance.
If you truly want to make this game something you enjoy for your whole life, develop a style that you enjoy and that works for you, and then work on improving that game, not some other game that some better player happens to have.
