Be honest: Are you working at your absolute peak? Just look at people like Angela Bassett, Jennifer Lopez and The Rock. They are able to look exceptionally good for their age and multi-task because they take care of their bodies!
That same idea applies to you as an entrepreneur. Treat your body well -- eat right, challenge your body, get proper sleep -- and you'll reward yourself with more energy, greater focus, and a heightened level of discipline. You'll achieve new levels of productivity while your competition falls behind and watches you scale faster and faster.
To put it simply: Sleep, exercise and nutrition are pivotal if you're serious about building a profitable, sustainable, scalable business.
Make your health a priority so you can make better decisions, keep a level head at all times, and scope out new ways to make money and expand your empire's influence and impact.
