To know oneself, one should assert oneself.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
Only the educated are free.
It often takes more courage to change one's opinion than to keep it.
