Know or listen to those who know.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

If you think you can do it, you can.

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

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

Without hard work, nothing grows but weeds.

By failing to prepare, you are preparing to fail.

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