Know or listen to those who know.

Quality is not an act, it is a habit.

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

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

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

Things do not happen. Things are made to happen.

It's always too early to quit.
