is it time?

Its been a long day at work.. Tired, yet went to practice, then had coffee at starbucks.
thoughts just kept flying through my head. Thinking. I don't even know where this thoughts are going. I dont even know why i tend to make it harder for myself when i can just walk away? hmmnn when should i do that? how do we know when its about time to STOP? why am i having a hard time to do so? Past stuff was easy to just walk away from, and yet now i cant do it? Is'nt it supposed to be past experiences makes a person wiser? Yet i dont know if im getting any. Whats the next step? Should i always be in the waiting list?
