You never know what motivates you.
The secret of getting ahead is getting started.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Never complain and never explain.
Because of my medical and ideological training, I am accustomed to saying that life is adaptation and symbiosis.
