If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

Be thine own palace, or the world's thy jail.

It's always too early to quit.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Always desire to learn something useful.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.
