If this sounds like your week
Soft timers negotiate away.
If pause and quit are always effortless, the timer may be helping you abandon the block. For serious sessions, commitment needs friction, and that friction should be chosen before the hard part starts.

Negotiation is the failure mode.
The most tempting time to quit is usually after the block has started. That is why commitment tools have to be configured before motivation drops.
Strict Mode fit
Casual block -> pause if needed Serious block -> choose Strict Mode first Emergency -> do not use strict tools casually
