Says

Flick:

Now do you see that tree?
Everything that made this giant tree is already contained inside this tiny seed.
All it neesa is some time, a little bit of sunshine, and rain, and VOILA!
Okay, you might feel like you can't do much now, but that's just because, well, you're not a tree yet.
You're still a seed. You just have to give yourself some time, and if you believe in yourself,
you can do anything.
