The first minutes of the day set the pace for everything after them. A short routine, finished before any app opens, keeps that time for you.
Keep the routine smaller than you think
Pick one thing you can finish in ten minutes. Stretch, write three lines, or make the bed. The point is to complete it, then unlock everything else.
Put the phone out of reach
Leave it in another room until the routine is done. If that is hard to stick to, block the apps that usually pull you in until the routine is checked off.
