It's always too early to quit.

Begin to be now what you will be hereafter.

Without hard work, nothing grows but weeds.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

You never know what motivates you.

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

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.
