Being an entrepreneur is not at all an easy task. When you choose to fend for yourself in business, the only person who can be blamed for failures is yourself. The entrepreneurial lifestyle requires a lot of patience, perseverance and above all concentration. Sometimes that leaves little or no priority to the most important aspects of life, like our physical and mental well-being.

Exercise at least 30 minutes a day

Making time to be active daily benefits your brain in many different ways. Exercising regularly is one of the easiest and most effective ways to reduce symptoms and improve focus, motivation, memory and mood.

Studies show that every time you move your body, a number of beneficial neurotransmitters, including dopamine, norepinephrine, serotonin, and acetylcholine, are released in your brain. A curated review published in the journal Translational Sports Medicine found that it only takes two minutes of exercise to temporarily boost memory and overall brain function.

Regularity is essential to stay in shape. "You have to keep your mind and body focused. Almost every time I get in a good mood, it's usually because I'm not training," Oppenheim said. The proximity was also a game-changer for Oppenheim, who walks 100 feet to a building next to his office to train.
