Expect problems and eat them for breakfast.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
I can, therefore I am.
Always desire to learn something useful.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
Imagination is as vital to any advance in science as learning and precision are essential for starting points.
