It's always too early to quit.

Quality is not an act, it is a habit.

Begin to be now what you will be hereafter.

Without hard work, nothing grows but weeds.

Know or listen to those who know.

The most effective way to do it, is to do it.

If you think you can do it, you can.

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

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