Seneca spent years writing letters about the mismanagement of time, but his sharpest observation wasn't about productivity — it was about what he called *aliena negotia*, other people's business. He noticed that intelligent, capable people routinely gave their best hours to tasks that were genuinely someone else's project, while their own meaningful work sat perpetually in the queue. The project management version of this is subtle: it's not just the meeting that shouldn't have been a meeting, but the entire initiative you're resourcing at 80% when it should be someone else's 100%. Seneca's prescription was blunt — inventory your days not by what got done, but by who actually owned what got done. If a large portion of your completed work belonged, by rights, to another person's purpose or role, you haven't been productive. You've been borrowed. For a father especially, this cuts deeper: the hours reclaimed from aliena negotia are the only ones that were ever truly available to give somewhere else.

If you listed every active commitment you're carrying this week, how many of them have a clear owner who isn't you — and what's keeping you from returning them?
