I've got almost 20 years in IT, mostly in various aspects of security. I don't consider myself complacent at all, but at the same time I'd much rather work the 9-5 M-F then put in lots of hours. In my 20's I thought that the more hours you worked, the more it showed the company that you were valuable. Sure I got top ratings but I was only focused on my career. These days I consider it a source of pride that my overtime for last year was less than 10%. I'd rather spend time with my wife, with my friends, doing things that are fun. I stopped working to work and now work to enjoy life. I'm so much happier and the hours I put in our more productive, after about 10 hours pretty much everyone is better off calling it a day.
