Me, personally
-broke my vow to not have sex because I was afraid I will never get it if I go bald
-almost dropped out of college because of the depression it caused me
-have been in toxic relationship, because I was afraid I will never have a girlfriend again
-hit a wall a couple of times
The dumbest thing I ever did was enlist in the Marine Corp. I had a full head of hair before that so maybe it's a chicken or the egg thing.
Wait to shave my head until I was 29. Should have been a few years before. 27 at most.
Could have saved myself years of doubt and replaced them with years of bald confidence.
