Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
If you've got a talent, protect it.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
You never know what motivates you.
The secret of getting ahead is getting started.
Leave the atom alone.
