Know or listen to those who know.

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

You never know what motivates you.

If you're going through hell, keep going.

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

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.
