It's always too early to quit.

The secret of getting ahead is getting started.

Know or listen to those who know.

If you can dream it, you can do it.

By failing to prepare, you are preparing to fail.

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

Without hard work, nothing grows but weeds.

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

To know oneself, one should assert oneself.
