If you are doing 40 hours in a lot of places it means you slack. I also see recommendation on HN for things like "if your company is switching to a framework you don't know you should spend nights and weekends studying it". How about no? Each hour I spend the less money I make for my time. I have other things I like in life and work serves to allow me to do those.
