Strength is measured not only by your physical attributes but also your emotional & mental fortitude to handle and overcome adversity. Rest not only helps your muscles to grow but allows your mind and heart to grow as well.
Top performers not only have the physical attributes to achieve their goals, they also have the mind set and passion to drive them towards success. Not only is rest required for your muscles to grow and operate efficiently, it is also required for your mind and heart to think and see clearly.
Stop chasing one aspect of the spectrum, rest is critical for success. If you are on the opposite side to much rest, determine what you want, why you want it, and drive yourself to make the change. Nothing comes easy and nothing happens over night remember #1percent each day is all you need to grow and change.
