To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
If you think you can do it, you can.
The most effective way to do it, is to do it.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
If I had not some strength of will I would make a first class drunkard.
