“Brainstorm when tired. Ron Friedman, author of ‘The Best Place to Work’, explains our fatigued brains are less capable of filtering out all the weird stuff, like we are during the day. He suggests finding that time when you’re tired and less focused to box off that time for creative brainstorming.”

Tired is when I’m least likely to ‘plan’ and ‘think hard’ because it feels like it’s going to take energy I don’t have, take too much effort. But it would mean that my thought filters are tired too and so perversely it’ll take less effort to get to outlying thoughts, if I can get myself over the hump of starting.
