“Never let them persuade you that things are too difficult or impossible.”

Good luck, old lad. Don’t listen to anyone who tells you that you can’t do this or that.  That’s nonsense.

Make up your mind, you’ll never use crutches or a stick, then have a go at everything. Go to school, join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible.

Douglas Bader’s advice to a New Zealand school student in 1954, who had lost his legs.
