I have been pondering this question for the last 11 days and I came up with a very interesting answer: It wasn't at all a waste. I have had so many experiences that I have actually learned from, become stronger because of, am able to admit my shortcomings without fear, and I am also able to reflect on all my accomplishments. It is incredible how powerful focus is. In the past I would have just focused on my shortcomings, but it is really all the good you take away from your experiences. Isn't it?
