While we tend to work while being sick, and push through to complete projects, it’s like the first thirty seconds after you’ve pushed yourself past an exercise goal. I’ll use a rowing machine as an example. After rowing for x amount of time, you get tired, and when the goal is y amount of time, after crossing that threshold it’s like a moment of clarity. You just gave all that you thought you could. There is a minor deception within that feeling, however.
