I’ve known several small business owners that that end up burning themselves out because they've worked so many hours a week and so many weeks a year. Even when they supposedly “take a vacation,” they’re still mentally working.
One of my most favorite books is "The Power of Full Engagement: Managing Energy, Not Time, is the Key to High Performance and Personal Renewal", by Jim Loehr and Tony Schwartz. The authors recommend balancing energy expenditure with intermittent energy renewal. Most people think about managing their time and don’t consider managing their energy.
Small business owners need to recognize the value of taking time out to renew their energy. Doing so will help them to be more physically energized, more emotionally connected, and more mentally focused.
