This rings true to me, perhaps because I struggle with this one.

I used to think I was destined for success, because I'm good and creative at many things, and am curious and can teach myself things.

But: I expected the system to integrate me. I realize now that, unless you're lucky, it's up to you to integrate yourself into the system.

It's a bummer to be underpracticed at this, and to be integrating suspiciously late. Feeling your potential, your ability to create great value for the system (while hopefully inspiring the system to also take good care of you). But instead only tapping a small fraction of your capability, because you haven't managed to link yourself in right.
