Either you run the day or the day runs you.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.

The most effective way to do it, is to do it.

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

It's always too early to quit.

Quality is not an act, it is a habit.
