When you feel like giving up and just locking yourself away what keeps you from just quitting everything?
Is it necessity or maybe you think of the consequences?
Do you think of payday or graduating whatever "reward" applies?
Is there a family member or important person you think of that you want to make proud or not disappoint?
Maybe you just do it because it's what you've always done?
Obviously this question doesn't really apply to people who are hardcore NEET and have already given up.
