The sentiment I have is that of the 30 year old. When I was 19 and working as a hardware and software designer at a start up, my boss found out that I had come in on a Saturday and worked all day. I thought it was cool and awesome to design hardware, and then write the firmware for it. He was #5 out of 120 employees with 20+ years of experience. He took me to the side and said, one day, you will have a family. Working on the weekend and long hours should not be something you strive for. He worked 9 to 5, and so did the rest of the team. I'm 33 now and have a 2 month old. I work 9 to 5 Mon to Friday. No more, no less. His was the best advice ever given by a manager of mine. Only took me 14 years to "get it" :)
