When I'm...
When I was 30, I knew who I was and how my life should go.
By the time I was 40, almost everything I knew at 30 was shown to be wrong and had been completely flipped on its head.
Now I'm... well...
...and I maybe-almost have it figured out?
BTW: I celebrate my birthday on Thanksgiving, because I was born on Thanksgiving. The exact date is not as relevant.
