Never complain and never explain.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
Well done is better than well said.
If you can dream it, you can do it.
Begin to be now what you will be hereafter.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
