Let imperfect action preserve continuity.

Continuity is more valuable than quality on any given day, because continuity is what makes future quality possible. A rough, unsatisfying session keeps the chain intact and keeps the work in your mind. A skipped session preserves your standards and costs you the thread.

When the choice is between doing it badly and not doing it, do it badly. You can improve a session that happened. You cannot improve one that did not.
