Speaking to yourself in the third person makes you wiser
The most damaging advice I ever got in my life was to talk to myself.I have always thought in mostly visual/symbolic terms. This made me really good with math early in my life, but it started failing when I began proof writing. Then I got the advice to "explain the problem to yourself and the solution will come naturally" from a friend who is really gifted at mathematical proofs. (And also later received similar advice in programming in the form of "rubber duck debugging").Surprisingly, it works remarkably well and probably increased my problem solving skills tenfolds, or at least my ability to communicate the answer. I started using it for everything.But it comes with the side effect of gaining a voice in your head. And that voice is a fucking vicious asshole to me. In the recent years the thoughts even started subvocalizing and I have to forcefully remember to make it stop. It's super embarrassing when there are other people around you.I am sure this problem is unique to me because I have never heard someone describe it (other than partially matching symptoms of schizophrenia or tourette). But I am certain in my case when the voices started and I am not sure the superpower problem solving skills are worth the trade.
