Do what you can, with what you have, where you are.
Ursula Franklin, OC, expanded on this approach:
From earthworms we learn that before anything grows there has to be prepared soil. When we talk about the endless process of bringing briefs and information to government, the only thing that can keep us going is the notion that it prepares the soil. It may not change minds, but it will provide the arguments for a time when minds are changed. Unless there is that prepared soil, no new thoughts and no new ways of dealing with problems will ever arise.
