In the deep end of the pool you can't touch the bottom, you must be constantly active, alert & aware.  I've always committed that I would be the guy who owns the deep end of the pool.  I'm obsessed with hydration, breathing, nutrition and moving my body in the right ways.  I don't ever want to lose my intensity and my presence in my company, or my personal life.  Is your company growing the way you would like? Are your actions moving your forward and having the desired effect?  If the answers are no, look at how you are taking care of yourself, how long can you keep treading water in the deep end?
