Don't End The Week With Nothing
"I used to be a salaryman at a Japanese megacorporation. The social expectation is that the company insulates the employee from all risk, and in turn, the employee swears themselves body and soul to the company. I worked 70 to 90 hour weeks for three years. This isn't particularly out of the ordinary for white collar employees in Japan. It didn't strike me while I was a salaryman that I was going to continue doing it until retirement, largely because the amount of work was killing me, and I worked after those hours on my own projects. Somebody asked me recently how I managed to stay motivated to work for the 91st through 95th hours every week. Answer: because I wanted to end the week with something."
