A great part of success involves perseverance. He who perseveres will usually reach his goal. But persevering can be one of the most difficult things to do.
The greatest test of faith is the time between the prayer and the answer to the prayer. It is during this interval that the battle of faith is won or lost.
It is also during this interval that the enemy will do his utmost to rob you of your faith through discouragement, doubt, and seeming defeat.
What you do during the test of faith will determine your success or failure as a writer. So be strong, and choose to persevere no matter what.
