Vacations don't offer themselves to the busy entrepreneur. It's up to that person to draw the line in the sand and dictate when they will take a sabbatical.
If you don't aspire to travel the world, or perhaps you are satiated by the amount of travel you carry out through business, I understand why you wouldn't take the usual two week vacation time.
But that doesn't mean you don't need a refresher from time to time.
Take a few days for yourself. Spend time with your family. Relax.
