to get better at starcraft, there's two things you have to do:
1. play
2. think
the play part can be done individually. it's the thinking and analysis of your game and what you need to work on that other people can help you with, i don't think someone else can help you play the game. although a coach figure would be of great help. you should find someone to talk to about starcraft alot. that, and take time to think about your games.
but, everyone learns differently, if it works for you, then power to ya.
