Yes, I experience this exactly. In solitude I can sit and work on a challenging task for 12 hours or more, falling asleep with my laptop and picking up where I left off upon waking. I’m so into it I forget to eat and shower. I remember hearing a story about a guitarist who was trying to play his scales as fast as possible, and an observer described it as the guitarist being so focused “he forgot to breathe”. That resonates with me. But if I’m sitting around in the evening with the family, I can’t achieve anything like this level of focus. I’ve come to think of it like an airplane or rocket. It uses most of its energy to get off the ground, but once in motion high above the earth, it can stay in motion using a fraction of that energy. Being around other people who might interrupt is like launching a rocket, and 3 minutes into the flight we have to land because someone wants a snack. Sometimes when I try to think about something challenging in these circumstances, in a matter of 20 minutes I feel exhausted to the point it’s hard to keep my eyes open, as if I’ve tried to launch a rocket every 2 minutes and have no fuel left, even though I haven’t gone anywhere.
