I seem to go in phases. Sometime I will really get into some physical activity, be it skateboarding or swimming or working out a specific way, and my mind will only want to do that, watch videos, read about it. I will have to force myself to stay on top of other things like work, life admin.
Conversely there are times where I'm really excited about something I'm tinkering with intellectually. Maybe a new library or some new approach to working, and I will have to drag myself to the swimming pool or the skatepark (well, maybe not the skatepark, but you get the idea).
And the funny thing is that in order to be happy and perform well at either of those extremes, getting myself to do the opposite thing is exactly the thing that will allow me to continue.
It's like in order to protect flow state, you need to strategically work against it.
