Be kind whenever possible. It is always possible.
Never complain and never explain.
Either you run the day or the day runs you.
Do not weep do not wax indignant. Understand.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
If you think you can do it, you can.
One reason the human race has such a low opinion of itself is that it gets so much of its wisdom from writers.
