‘Return to calendar’ is a mantra to get you from a confused, multitasking state back to the one thing you’re supposed to be doing at that time. I often say it out loud to make it happen with more conviction, faster. I also sometimes say to myself ‘One thing at a time’ to achieve the same end.

The trick and the skill is to give yourself every chance of noticing when you start to get distracted which is difficult, by definition.

A screensaver, like the one below (generated by DALL·E 2) is one tool that can help. Seeing it will sometimes awaken you from your distracted stupor and bring you back to your calendar. If you create your own image, the effect is likely to be better still.
