What you do today can improve all your tomorrows.

I can, therefore I am.

Things do not happen. Things are made to happen.

If you can dream it, you can do it.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.

Quality is not an act, it is a habit.

After a storm comes a calm.

To know oneself, one should assert oneself.
