Know or listen to those who know.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
You never know what motivates you.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
If you think you can do it, you can.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
Stronger by weakness, wiser men become.
