To know oneself, one should assert oneself.
What you do today can improve all your tomorrows.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
You never know what motivates you.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Why not whip the teacher when the pupil misbehaves?
