When your natural inclinations are blocked, drudgery takes over, and the smallest tasks become major efforts. When you are truly engrossed in an activity, life is exciting, and energy flows naturally into your efforts. Examples of this seem to crop up continually. If your car mechanic enjoys his work, the slightest hint of a question will propel him into an animated explanation of the most obscure details, yet, if he is only concerned about the weekly pay check, grunt responses and minimal effort will be the norm. His enthusiasm means you get high quality work, and he succeeds in his business.
Enthusiasm breeds success.
If you are enthused, technically capable, and mentally prepared, you have a major advantage.
