It's just 8 hours a day. 5 days a week. Roughly 25% of your life. Another 33.3% is spent asleep. Maybe you commute to work; maybe that takes you 45 minutes each way. That's 4.4% of your life spent driving, walking, on trains or buses to get to your job. You're going to spend a small percentage of your life on the toilet; another small percentage in supermarkets buying food, in a kitchen preparing it, or in a dining room eating it.
All the 'big events' in your life will be squeezed into the precious little time you have left after survival's necessary subtractions. Going to school. Getting drunk. Being hungover. Getting married. Buying a house. Attending funerals.
Perhaps we were thinking in similar terms. You took those thoughts—nay, facts—and channeled them into a manifesto which guides your relationship with your employer.
Here's what I did with the same facts. I decided I'm not spending over 25% of my life (37.5% of my waking life) doing something I don’t LOVE. For comparison, if I find a spouse, it's likely I won't spend 25% of my life in their company. So if I'm going to spend more time at work than I will with my future husband, I need to love my job at least as much as I do him. That's the conviction which caused me, just a few hours ago, to hand in my notice of resignation to my current employer. Because when I find myself watching the clock waiting for 5:01, I must concede that 25% of me (37.5% of the waking me) has already died.
This isn't a judgement. I respect you for your decision. There's probably some pity in there too, but honestly, it's mostly respect.
