Explore-in-Expand reminds me of Ergodicity by Luca Dellanna. To improve the survivability of a large-scale goal, reduce the survival of sub-goals. If I have a sub-goal that can’t fail without taking down the whole goal, I’m at big risk. If I restructure the goal so that any 1 of 3-4 subgoals needs to succeed, I’m much safer (this is what I’m doing with my career right now).
