It's always too early to quit.

If you think you can do it, you can.

Begin to be now what you will be hereafter.

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.

Know or listen to those who know.

To know oneself, one should assert oneself.

If you've got a talent, protect it.

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