The scariest thing is to realize that we are weak and stupid. And we are hiding it from ourselves, even though we feel it deep down. But if we don't understand it, we will never progress. And the thing is, it is okay, everyone starts somewhere. No one is born strong and intelligent.

So, to grow up and progress, we need to realize that most things we know are probably delusional, and we don't really understand anything.

Then, we need to start learning things with open minds, trying to understand how things work, not just memorize information said by 'smart' people.

And of course, try and experience it personally...
