Start thinking like a radical pragmatist: still ambitious, aggressive, and rooted in ideals, but also imminently practical and guided by the possible. Not on everything you would like to have, not on changing the world right at this moment, but ambitious enough to get everything you need. Don’t think small, but make the distinction between the critical and the extra. Think progress, not perfection. Under this kind of force, obstacles break apart. They have no choice. Since you’re going around them or making them irrelevant, there is nothing for them to resist.
