"You are NOT going to improve yourself."
...think carefully about this...
"The part of you that wants to do the improving is exactly the same as the one that needs to be improved."

You are what you are, and that is all you will ever be.
You're unsatisfied with who you think you are because you only allow yourself to BE who you think you are.

You are more than who you think you are. You're not just your conscious self. That's just part of the whole. There are unconscious, semi conscious (instinct), and super conscious parts of you.
As your IQ can never improve from 90 to 200, so also you cannot become someone else.

The self improvement myth is a pseudo-journey towards allowing yourself to BE.
You cannot improve, you can only be. You've always known how to drive, just as you've always known how to walk. If you could never do these things, you would never do them.

There is no better version of you. Better at what exactly? And who decides what's better.
I repeat...
You're more than who you think you are, you're more than what you know. Until you allow yourself to be, you will be unsatisfied, thinking you need to improve. But you can't.
