All professionals - Project Managers, Program Managers, Executives, leaders of all kinds - worry at times, and some more than others. Worrying a lot or a little is actually a controllable habit. Worrying a lot is little more than trading your peace of mind and taking a negative view of the future. The urge to worry can be useful in alerting us to possibilities to manage, but worrying is needless, and the cost is very steep, often the cost of actually bringing our worst fears to reality.
