Never complain and never explain.
Expect problems and eat them for breakfast.
I can, therefore I am.
After a storm comes a calm.
If you're going through hell, keep going.

Be thine own palace, or the world's thy jail.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
Always desire to learn something useful.
