I would recommend watching some existentialist and absurdist work.

The idea of we are born with meaning and purpose is a wishful one, hence most people feel lost once they realise that isn’t the case.

But existentialism etc argue that makes our lives more authentic and more free to do anything we actually want.

Unlike religion that gives you an ultimate purpose, that you must abide for the better eternal life, a meaningless life means you should enjoy the one you have right now.
