1. Play lots of 30/0 live chess and review your games with a chess program.
2. Read a good chess book for positional/strategic understanding (like Silman's reassess your chess)
3. Spend every waking minute of every waking hour doing tactical puzzles until you see the dance of the chess pieces in your dreams...
