Always desire to learn something useful.
It's always too early to quit.
Things do not happen. Things are made to happen.

If you think you can do it, you can.
The dog that trots about finds a bone.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
The physician's highest calling, his only calling, is to make sick people healthy - to heal, as it is termed.
