Valve – Handbook for New Employees (2012) [pdf]
I find the whole "You are a person who spend every waking hour optimizing yourself to become the best YOU you can be"-frame of mind very intimidating. Maybe it's because I'm not american, but even though I like to work with complex issues, I also like a 9-17 job with a decent income, and the ability to go home and relax when I'm not working. And by relax, I don't mean working on side projects, doing volunteer work or earning a second degree in something. But playing board games, working out/running or even just watching mindnumbing TV. I feel like the "100 % dedicated 100 % of the time"-thing has become the only way to really make it in tech-life.
