The one tool that earned its place this month.
Not the perfect system, not the thing that's "supposed" to work โ the one thing that's actually still in your life a month after you started it, doing its job without you fighting it.
Mine right now: a kitchen timer I can physically see counting down, sat on my desk. Sounds stupid simple. It's the only thing that's made "now" and "not now" feel real enough to act on.(you'll know what that means if you've done Day 1 of The First 5 Days).
Your turn โ what's earned its place? Doesn't have to be fancy. The boring ones that actually stick are usually the most useful thing anyone in this thread will read.
