Don't get caught up on the little things (unless it's a security issue or something else with that level of severity), and always take a break and come back later.
Also, for general productivity, I like to do a more extended version of the pomodoro technique; I work for 54 minutes, then take a 6 minute break, and every 3 hours I get a 15 minute break (but I normally cheat and take a 30 minute break :p). This method is nice because it allows me to be hyperfocused for a certain period of time, and then completely relax and unwind without wasting too much time. It's also awesome for long days.
