It's always too early to quit.

If you think you can do it, you can.

Either you run the day or the day runs you.

Begin to be now what you will be hereafter.

Leap, and the net will appear.

If you're going through hell, keep going.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

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