A classic : My friend told me

In your life, I liken you to the bumblebee. In physics, the bumblebee is an enigma because its wings are too small for its body and it is not supposed to be able to fly. They say that the bumblebee never studied physics and it didn't know that it couldn't fly, so it flew. "So it is with you and the many challenges you have overcome. You have done so many things that couldn't be done, because you too, didn't know that they couldn't be done. And you did them over and over, and better and better. The bumblebee keeps flying and you keep growing."
