"The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."
— George Bernard Shaw, Man and Superman (1903) "Maxims for Revolutionists"
If you acknowledge the need for change, sometimes sharp change, then there is a thin line separating the reasonable and unreasonable. What may be a sound plan for change can easily top over into an absurd, unworkable notion.
Or at least some of the stakeholders involved will think so. This means that fostering change–the change we may need–can mean being distinctly, noisily, objectionably, unreasonable. If you go there for good reason, I've got your back. You're likely to make a difference.
