In addition, to keep your energy levels at their highest, be careful
about what you eat. Start the day with a high protein, low fat and
low carbohydrate breakfast. Eat saladswith fish or chicken at lunch.

and candy bars or pastries. Feed yourself as you would feed a world

what you are before starting work each day

farther when the wheels are in perfect alignment, you perform better when your
thoughts, feelings, emotions, goals, and values are in balance.
