Things do not happen. Things are made to happen.

Expect problems and eat them for breakfast.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.

It's always too early to quit.

If you think you can do it, you can.
