I myself recently realized that I wanted to transition from being a manager - cutting time into small readily accessible chunks - to that of a maker - one whose time cannot easily be divided into anything more than half day chunks.
The journey has meant saying no to a lot of nice but not essential meetings and a transition time of nothingness. By that I mean time that I haven’t yet got the energy to make use of or the peace to see what I wanted to do.
Now I can create value the way I’ve wanted to for years without fear or distraction. It doesn’t necessarily mean you’re shut off from the world, just that the inputs in your day aren’t unrelated to the project or service you provide.
