Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
It's always too early to quit.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
