It's always too early to quit.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.

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

Be gentle to all and stern with yourself.

If you can dream it, you can do it.

The secret of getting ahead is getting started.
