If I'm avoiding something, I can decide to do just a tiny bit of it. Sometimes, it can get done in 5 minutes, whether it's making a dreaded phone call, or paying bills, or cleaning a messy desk. If the task is a bigger one, the 5-minute trick is sometimes all it takes to get rolling, if done enough times. Just 5 minutes is the difference between being sedentary and being not-sedentary, for instance. And, it can get me on my way toward a good, steady habit of being more physically active.
There's another good thing about the 5-minute trick. Endless to-do lists and lofty goals are usually self-defeating for me, because they can add up to a long string of failures that only serves to taunt and harass me. Building a mountain of little successes sure feels a whole lot better. As the old saying goes, "From small beginnings come great things."
