I never make the same mistake twice...!

87% of youngsters are suffering from back pain. 

It's the people who try to be clever, who never are;
the people who are clever, never think of trying to be.

I never make the same mistake twice.  I do it five or six times, just to be sure.

My room is not really messy it's an obstacle course designed to keep me fit.

When I count my blessings, I count you twice!
