I’ve found my fellow entrepreneurs to be some of the most energetic people around. Some maintain that energy more healthfully than others, but most of us wouldn’t have achieved our success without being able to tap into a high level of energy when we need it. The trick, I believe, is to figure out how to generate that energy in a way that is self-sustaining. Here are a few behaviors that I’ve found to help us perform at our best.

Hydration
I try to drink at least half my body weight in ounces of water every day. Water is a primary detoxifier, transports nutrients to all tissues of the body, regulates body temperature and increases metabolism. Water also increases our overall blood volume, and thereby increases the delivery of oxygen to our brains and muscles. Dehydration is a leading cause of daytime fatigue, and is often mistaken for hunger. I believe that staying hydrated is one of the most important things I can do to stay energized and mentally alert.
