To know oneself, one should assert oneself.
Do not weep do not wax indignant. Understand.
Be gentle to all and stern with yourself.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
After a storm comes a calm.
The dog that trots about finds a bone.
Only the educated are free.
If you think you can do it, you can.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
