That is much like suddenly deciding to scale Mount Everest, having never been rock climbing. Be reasonable and be fair to yourself. The fear of uncertainty that often accompanies new ideas, new processes or procedures, and new jobs need not immobilize you. A good technique to use in managing fear is to actively visualize yourself facing and overcoming it. When faced with a large, complicated, or time-consuming project, break it into small, manageable parts.
Smaller tasks are attractive because they are short and easy, and produce immediate gratification.
Keep in mind that all tasks, no matter how massive, are only a series of small items reassembled. Ask others to become involved in your efforts. Assistance in reviewing progress, setting realistic deadlines, or strategizing an approach to a problem can be very helpful. You may be too close to the situation to be objective. One of the best ways to break the procrastination habit is to reward yourself for good behavior.
