Success is not final. Failure is not fatal.
It is the courage to continue that counts. Winston Churchill
Love your signature line!
Agree with the sentiments expressed by you and the others here too - too often people don't let kids understand that frustration is a normal part of life and you'd best learn to handle it.
A young couple I know "practised" walking with their young child every day because the child didn't like to fall and would cry with frustration. When I said I didn't think any kid I ever knew had to have their parents' "practise" with them, I got nasty looks. Should have used my inside voice I guess!
