I used to dwell on this, because I was not able to live up to my potential, and that really sucks. I'd be much farther ahead in life and much more fulfilled. But it is what it is, and it's a waste of time to dwell. I just focus on what's possible now, and the positives in my life. I just hope when I'm at the end of my life, I am at least somewhat satisfied with how it all turned out.
