People who are self-identified incels or incels by the traditional definition just simply do not try hard enough to be happy.

They do not do anything to improve themselves, they usually say they do, but I have my doubts. Instead a lot of them go on forums and subreddits such as r/Trucels or r/Foreveralone.

I think if incels actually gave it their all to improve, they would be able to, but they'd rather just sit there and complain.
