Be gentle to all and stern with yourself.
If you can dream it, you can do it.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
What you do today can improve all your tomorrows.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
The wise does at once what the fool does at last.
Never complain and never explain.
Only the educated are free.
Moderation is the inseparable companion of wisdom, but with it genius has not even a nodding acquaintance.
Doubt is the vestibule through which all must pass before they can enter into the temple of wisdom.
