It would be nice if I was able to use some kind of ESP. It would be a lot nicer if I was able to use it without any risk. The hell it would be if I was able to use something like kamehameha in exchange for my life or able to use an ability to lose my hair without getting any stronger.
It might be a nice power though. No need to go to the barbers, shiny head. If there was something like strongest power with that, I would probably be satisfied.
