Momentum isn't good on its own.

Momentum is great when it's pulling you towards a great outcome.

But momentum on its own is just a coherence in motion on the team.

The coherence can become a kind of rut.

Sometimes the coherence emerges organically in the absence of a viable vision.

Often the thing it coheres around is the charismatic traps: the kinds of puzzles that seem important and are fun to solve… and also are vast, dangerous jungles of compounding unknown unknowns.
