If you're a change agent and you're feeling a little uncomfortable with the risk you're taking, you're in good company. Because most people resist change at all costs, you're in the minority as a change agent. Consider these words from Niccolo Machiavelli: "It must be considered that there is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things." Your uneasiness should not be a deterrent, though. If you've done your research, weighed all the options, and believe the direction you're heading remains the best or appropriate direction, then Godspeed to you.
