No one likes change; it rarely comes easy. Slowly incorporating small steps toward your goals overtime leads to huge changes in the long run. Many people jump, headfirst, onto the diet bandwagon around the New Year, but don't. Adopting too much change at once often leads to burnout. Instead, outline your short-term goals, achieve them slowly, and you'll soon find success.

When is the last time someone took a candid picture of you? Do you notice yourself slouching in the image? Aging drags the shoulders forward and the head down, putting undue pressure on your spine and nervous system. But don't worry; you can start correcting your posture today with this simple change: While at the computer, sit upright with your head looking up at your monitor, instead of down, keeping your back straight up against your chair and your feet on the floor. Adjust your monitor so your eyes are level with the bottom of your screen.

Several recent studies show a clear relationship between how many hours we sit each day and a decreased life expectancy. You don't need a gym membership or fancy home equipment to be active. Park farther away from your destination or take the stairs. If you sit at a desk each day, walk around your office for at least five minutes every hour and consider marching in place while taking phone calls.
