Hey there,
Sometimes the absolute best thing you can do for your productivity is noodle the afternoon away on your instrument.
The only reason I have a life in this business is the hours, days, and years spent completely wasting time on my guitar.
It's not just a good idea, it's a requirement. Take a break.
My bookshelf is full of productivity books, btw. I'm currently reading Deep Work by Cal Newport. It's great. I need to read it. It will help me, if I let it.
But art is about discovery. Trial and error. Yet my day is filled with To Do lists and tasks that must be perfect.
That's just life. Adults are expected to be perfect, at least some of the time.
I'm getting better at knowing something is worthwhile even when there's no way to track its value on a spreadsheet.
Most likely you're thinking about something very specific right now. Pencil it in after lunch.
Talk soon,
Jon
