I think the bio will add 0,01 % to your " gains" ,but simultaneously will cost you tons and tons of " doubtful p00sy ". ( he was okay ish untill he opened his mouth- idea)
Most of the time a bio comes across as planet try hard.
Read my 9,8 or zero thread..same principles apply but now on steroids.
No woman who isn't into you will read your bio. And if she does it gotta say something ridiculously high status that you somehow couldn't capture with your photos. Like" graduated *** laude at Harvard" ..but that will attract fold diggers...
Catch 22 it is Watson.
