I am sure there are, I do not know why you say that. Especially if you count those who did it at least a few times in high school, college and/or any other time in their 20s or early 30s.
Maybe you should read again what you posted:
“as for it destroying lives, well there’s thousands of people who probably are using it now and have used it and are still more productive and successful than anyone here on FR.”
More successful than anyone on FR?
“Anyone” is a very strong word, and, additionally, there are some pretty successful people here.
I’m not trying to nit-pick and neither am I mistake-free, but words mean things and what you post here will be taken more seriously if they are chosen with care.
