I’m not saying never let yourself be distracted.
I’m saying when you want to focus on some creative task then focus. Here’s a rule that will help.
Do the thing or NOTHING.
‘The thing’ is whatever your creative thing is, writing your story, sketching in your sketchbook, drawing your comic, whatever it is. If you’re serious about your creative work, you might call this your ‘life’s work’.
Not to stress us out, let’s just call it ‘the thing’.
Now when it comes time to do the thing. Find a spot that is not distracting or the best alternative, set a timer, then commit to do the thing or nothing. You are giving that distracting part of your brain 2 choices. Often it will choose to do nothing.
Let it, indulge it.
