Things do not happen. Things are made to happen.

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

If you think you can do it, you can.

Know or listen to those who know.

Be thine own palace, or the world's thy jail.

You never know what motivates you.

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