If I knew this was my last day alive, I wouldn't be here sitting at work. Living every minute as if it was your last is actually pretty difficult to do. Or perhaps it means coming up with the understanding that it's not worth your time to stress about work. Just do the work and focus on what makes you happy. Maybe even quit and live a simpler life with less income? But you usually have houses to pay, kids to raise... it can become a prison of its own kind. There's always some magical reward waiting just around the corner, be it retirement, kids moving out, when you can finally focus on yourself again. How does one truly live every moment like it was their last?
