The Longest Way is a Short Cut
Then [Saul] waited seven days, according to the time set by Samuel. But Samuel did not come . . . So Saul . . . offered the burnt offering. Now it happened, as soon as he had finished presenting the burnt offering, that Samuel came . . . And Samuel said, "What have you done?" 1 Samuel 13:8-11
One of the most common obstacles to success is the desire to cut corners. But shortcuts never pay off in the long run. If you find that you continually give in to your moods or impulses, then you need to change your approach to doing things. Cutting corners is really a sign of impatience and poor self-discipline. But if you are willing to follow through, you can achieve a breakthrough.
The best method is to set up standards for yourself that require accountability. Anytime you suffer a consequence for not following through, it helps you stay on track. Once you have your standards in place, work according to them, not your moods. That will get you going in the right direction. Self-discipline is a quality that is won through practice.
