If you think you can do it, you can.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
After a storm comes a calm.
I can, therefore I am.
Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
