Nir Eyal says distractions are actions that don't match your planned, value-aligned time. Schedule your values on a calendar in specific blocks. An open calendar makes everything feel like a distraction.
Making time for traction involves turning your values into time. So it's only by looking at your calendar and saying, ah, that's what I decided to do with my time and attention that, you know, what is traction and everything else that is not. That is a distraction. So if you have a big open calendar where you haven't decided what you're going to do with your time and attention, then everything is a distraction. Timeboxing simply involves planning out what you're going to do with your day. Planning out every minute, not every single little task.
