However you decide to manage your workload, please understand that working long hours without regular breaks is not sustainable. We can address this by working fewer hours in a day or fewer days in a week. Or we can merely get up from the desk and walk around a bit more when you notice that your productivity and energy levels are dropping. Getting outside for lunch and away from screens can also help.
The problem of just using fear for motivation is that it triggers our fight-or-flight response. It increases our cortisol levels if we trigger this response too often, so in the long run it isn’t so great for our mental and physical health.
