To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Wherever you are - be all there.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

Either you run the day or the day runs you.

It's always too early to quit.

Expect problems and eat them for breakfast.

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