It's always too early to quit.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

Wherever you are - be all there.

Things do not happen. Things are made to happen.

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