If you think you can do it, you can.
After a storm comes a calm.
Know or listen to those who know.
It's always too early to quit.
Begin to be now what you will be hereafter.
I can, therefore I am.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
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.
