This is possibly the best advice. Also: Think longer term now. My unit of time, as I got older, went from hours to days to weeks. Now, I say things like "I'll finish that next month." It's not necessarily that I do less, it's just that I cannot afford to fragment my days as much as I used to so I'm stricter with my schedule. In this respect, it makes perfect sense to allow yourself to think only about your job for, say, 6 months. When your mind wanders, right down the idea as something to come back to. Schedule, ahead of time, a day to just exist with your idea list and tinker a bit, every now and then. But don't expect to be able to follow your interests every minute. Self-regulating in this way is a super power that takes time to build up, but it's immensely rewarding when you can close something, turn to a new thing, and know you have the capacity to finish it.
