I certainly don't regret my experiences because without them, I couldn't imagine who or where I would be today. Life is an amazing gift to those who have overcome great obstacles, and attitude is everything!
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.
