This principle has served me well in the past:
Don’t split your attention!
I don’t check my phone when in a conversation. I don’t chat when watching a movie. I don’t listen to new music when writing, I don’t read when I listen to new music, I don’t clean the kitchen while listening to a podcast, etc.
On the flip side, if I feel that what I’m currently doing doesn’t deserve my full attention, I very much prefer looking for something that does …
… rather than split the attention with a second thing.
What’s your approach?
