The wedge
The wedge is the one habit narrow enough to win and strong enough to build on.
The wedge is the single habit we perfect first: small enough to get genuinely right, load-bearing enough that the wider product can grow from it. It is where end-goal-first thinking becomes a concrete decision.
Choose the wedge well and everything after it has a foundation. Choose it poorly and no amount of features will hold. So we choose deliberately, then we make it excellent.
