Don't.
It's a lie to keep you wanting something that nobody is guaranteed to find in life.

It's a lie that keeps you unhappy even at your best, unsatisfied, wanting something unneeded to live a fulfilled life.

It's a lie to keep you insecure, second-guessing your purpose, even if there are a million reasons to look at yourself with pride.

It's a lie that haunts you because you let it become the ghost of your life.
