Is 'mental endurance' just another way of saying 'I’ve debugged at 3 AM and lived to tell the tale'?"

Mental Endurance in Tech and Beyond

I stumbled across a discussion about mental endurance, and it got me thinking. In my own work, the long nights and intense focus required can feel similar to that “debugging at 3 AM” mindset. It’s less about brute force and more about sustained, calm problem-solving under pressure.

I’m curious how others define this kind of stamina outside of tech. How do you build and maintain that mental resilience, especially when you’re tired or hitting a wall? Are there specific strategies or mindsets that help you push through a complex task without burning out?
