If your high-powered job has you running from one board meeting to another, or traveling to different cities on a regular basis, then it is important for you to stay sharp. You cannot perform at your best if you lack energy. If fatigue has become your constant companion and you have become accustomed to starting the work day with a jolt of caffeine as you drive to work, then take heed - you need to find ways to gain more energy in a healthy manner. The best energy comes from eating the right foods.
