While I admire the dedication and focus it takes to stay up to such routine, I am certainly concerned by the quality of life and the narrow mindedness of enforcing upon oneself to code on a daily basis. What about days off? Going out friends / family for a weekend or holidays? One would suggest to bring your laptop so you can stick to it? This is madness to me...
I love to code, contribute to OS projects, do code for a leaving and for myself - but for nothing in the world I'd even attempt such thing.
Setting yourself with goals is great and required to some extend but on a proper schedule. Going to the gym 3 times a week can be achieved without being complexed by the fact you didn't go there every single day - and yet you can substantially improve yourself. I don't envy those buffy dudes that stick to it.
I'll stick to enjoying evenings with my wife, do code maybe 1 or 2 times during the week days, spend an extra day on more complex issues on the week end, and rest for the last day. Just saying.
