Expect problems and eat them for breakfast.

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

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

It's always too early to quit.

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

You never know what motivates you.

If you think you can do it, you can.
