The pressure to do more never really stops. It just changes shape.
As a dev, the question was nightly: could I finish one more task before logging off? Get a head start on tomorrow, or call it a day?
As a lead, the question became: could I push the team for more next sprint? We overdelivered. Do we stretch, or do we rest?
Same question, different chair. And the right answer is almost never obvious in the moment.
I've drawn the line too late more times than I'd like to admit. In the better moments, I've caught it early enough to change course. The difference between the two isn't willpower. It's inspection.
Not the Agile kind. The human kind.
Asking myself what's actually going on, not what I'm telling myself. Asking my team how they're really doing, not just how the sprint is progressing. And asking about things that have nothing to do with work at all.
People aren't resources. The language of capacity and velocity makes them sound like they are, but they're not. Two people sitting next to each other, doing identical work, can have wildly different limits on any given day. You won't know which is which unless you ask. And unless they trust you enough to tell you.
I don't always get this right. But the times I've got it most wrong have almost always been the times I forgot to ask.
