I had a conversation with my wife about this the other day. I look back on my 20s and realize that I was a baby and knew nothing. I'm 33 now and have grown and learned so much since that version of me. When I'm 40, I'll be thinking the same thing about 30 year old me. When I'm 50, I'll be thinking the same thing about 40 year old me. And on and on. The learning , the humbling, never stops and I'm ok with that.
