To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Do not weep do not wax indignant. Understand.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
It's always too early to quit.
If you think you can do it, you can.
Some folks are wise and some are otherwise.
