You manage to keep going harder if it’s important enough when it feels like you have no energy.
But we’re very bad at getting some rest when needed. Random thoughts come out of nowhere. There’s this constant paranoia that you need to do something, at least a distraction. Rarely do we get the feeling like when you’re by the sea. Of course, the obvious reason is the cue. You can’t get that in an office. Overworking is easy in that sort of setting.
