With warmer weather just around the corner, it will soon be time for the afternoon exit. Hobbies are an integral part of overall healthy living. Find something you truly enjoy, make time for it and dedicate yourself to improving performance. These times away from the daily grind and salt mine are not only refreshing but also enable you to get more accomplished when you're in the work arena. A hobby that requires you to push yourself and compete against others on time, score, weight, etc... will sharpen that killer instinct.
