Be gentle to all and stern with yourself.

You never know what motivates you.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

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

Things do not happen. Things are made to happen.

Be kind whenever possible. It is always possible.

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

Know or listen to those who know.
