Focus on what you can do rather than stress about what you have no control over.
Dream it. Dare it. Do it.
There are always more choices than you think.
It's OK to be down in the dumps - just don't stay there too long.
Belief in ourself is like a muscle - it is strengthened by constant and careful use.
'I tried and it didn't work' is a lot better than, 'I wish I'd tried'.
