Hurry is the death of Prayer.
The reason so many people do not pray is because of its cost. The cost is not so much in the sweat of agonizing supplication as in the daily fidelity to the life of prayer.
There is no way to learn to pray but by praying.
Praying solves the problems of prayer.
If you're successful, don't crow. If you're defeated, don't croak.
Prayer is the acid test of devotion.
