These regrets sound awfully metrosexual to me. I have none of those regrets. And I’m still alive. None of those regrets will haunt you if you stop giving a crap what anyone thinks of you.
I was telling my daughter (in the presence of my wife) how I had to wear leather dress shoes until I was a teen due to orthoditics that were placed in between the sole and the shoe. No sneakers until I was probably 15 or so. Lots of teasing, but they worked. (Now of course they make the ones that slip into the shoe!)
My wife quipped “No wonder you don't care what anybody else thinks about you.”
