If this sounds like your week
When quitting is free, you'll quit the moment the work gets hard.
Most focus timers keep pause and quit one click away. That feels harmless until the task hits its first uncomfortable stretch — and the easy exit is right there, inviting you to "just take a quick break" or restart later. The session you set is optimized to be abandoned politely.
Where tooling usually breaks
A focus session with an exit hatch is just a suggestion.
You've started the same block a dozen times this week and bailed on every one the instant something felt easier. Each bail is a fresh negotiation with yourself, and willpower loses that negotiation more often than not. The tool isn't on your side — it's neutral, which in practice means it sides with the impulse.
