Should life be taken seriously?

Ooookay joker. Say hi to batman for me next time you see him.

You're going to die in the end. No one will remember you, and those who do will die as well. Wind will fall and bury your bones.

All your failures will be forgotten, so fail as much as you can now in hopes to achieve something which will help people in the future. Only that would mean you life had a purpose.
