The basis of persistence is the Power of Will.
The man who actually knows just what he wants in life has already gone a long way toward attaining it.
If you pray for a thing, but have fear as you pray, that you may not receive it, or that your prayer will not be acted upon by Infinite Intelligence, your prayer will have been in vain.
Plan you work and work your plan.
Strength and growth come only through continuous effort and struggle.
First you get a habit, then it gets you.
