Have you ever heard the saying, "Much of will is skill"? Many times we mistakenly attribute someone's success to being "in the zone' or just sheer determination or willpower.
The reality is that success is the magnification of the skills that an individual already possesses. To get more out of your time, try doing things in intervals. This will help you stay focused, while also breaking the mastery of new skills into mini goals that are attainable.
Until next time, continued success!
