To know oneself, one should assert oneself.
Wherever you are - be all there.
It's always too early to quit.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
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.
