When Harry is all like, “The greatest witches and wizards started off as little more than we are now” (paraphrase, k). Well, take away the wizardry bit, and the exact same thing applies to you and me.
Everyone starts off as a kid without a clue. Why not be someone who does something about it? Become someone. Some day kids somewhere might wonder if you ever felt small like them. And the ones who realize you did might become something better because of it.
It’s just something I think about on the occasions when I feel like I’m “not good enough” to do whatever big, insane, or noteworthy thing I’m considering at the time. It really keeps me in the game.
Now go away so I can go back to doing nothing.
