To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Well done is better than well said.
Know or listen to those who know.
After a storm comes a calm.
Only the educated are free.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Doubt is an uneasy and dissatisfied state from which we struggle to free ourselves and pass into the state of belief while the latter is a calm and satisfactory state which we do not wish to avoid, or to change to a belief in anything else.
