Well, it's not really being "hard on myself." It's just a rather humorous reflection on me (and on others). One of the things that young folks do, is take themselves way too seriously. After we get some wrinkles and gray hair, we come to realize that a lot of life is paper tigers. There's plenty of stuff that needs to be taken quite seriously, but time allows us to apply a razor; cutting away the chaff.
Also, some of the best lessons I learned, were from ass-kickings.
"Good judgment comes from experience. Experience comes from bad judgment."
--Attributed to Nasrudin, but I read it from Will Rogers
Everything has worked out, the way it needed to, in order to bring me to where I am now.
I have no regrets, but I do get a chuckle or two, from reflection.
