Without hard work, nothing grows but weeds.

Know or listen to those who know.

What you do today can improve all your tomorrows.

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

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

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

The dog that trots about finds a bone.

To know oneself, one should assert oneself.
