Repetition Makes Perfect

Repetition repetition!
That's how I've had to learn everything in life. Apparently this is true even with my mistakes. Why can't I learn from past mistakes? Why can't I do what I know is right?... What I "think" I know is right...What I "want" to know is right. Apparently I need to figure out whats really important to me in life, and not just who's important to me....What will my life be about?
