The great and often quoted Jack Welch once said, Change before you have to. This short, simple sentence summarizes the most important characteristic of the entrepreneur: proactivity. Being proactive, obviously as opposed to being reactive, is the single most significant difference between those that succeed and those that don’t. Proactive mindset means that we look ahead, anticipate, plan, do, measure, evaluate and then….re-do as needed. And then, do it all over again.
