Just don't be naive and think that societal standards don't exist. And also, possibly give some thought as to why they exist so that you don't go down insane spirals and waste your life only to later understand that the collective had a point.
No argument here.
I'm saying you should examine why people set the standards they do and check if you agree with those values.
If you want to say "hell be with it, I'll be scum til I die because it makes me feel good" then more power to you. But don't go around saying you're successful. You're a rebel and a loser by most people's standards. Not by all. Even school shooters are respected by SOME for their bravery and determination.
