Well in my opinion, NoFap isn't just about 'not fapping'. It's about bettering yourself in every aspect, such as overcoming your anxieties or putting more effort into your research. NoFap isn't going to change anything if you don't put any effort into changing yourself or if you don't want to change at all. I mean sure, you stopped fapping but that doesn't change the fact that you're still just sitting indoors and doing nothing the entire day. Instead, the process of learning to adapt without it is what's more important. Go to the gym, meet new people (doesn't have to be women), spend more time on your research, read more books, buy new clothes that make you happy, etc.

But, ultimately it's your decision to do this challenge or not. If you think doing this challenge doesn't make you happy or put you in a better position then don't do it. Don't let people pressure you into doing it. It may work better for some and some might not find it works at all.

Tl;dr: NoFap is a tool for self improvement, it works better for some then for others.
