If I were to account for everything I had done so far in my life, there would not be much.  I've done a few things here and there, but have I ever truly lived?  Looking at myself, I see all sorts of missed chances and unfulfilled desires.  There are times, such as these, when I have a perspective on life that is conducive to fulfilling such desires, but, as luck would have it, these perspectives do not fit over my entire life, so while I may feel ready to take on the world at 1 am today, I probably won't at 7 when I get up.  And that's the way the cookie crumbles.
