How do you keep yourself focused?

[boldfacedesign]

As a fellow "frontend" developer with a passion for what I do and a large amount of curiosity I find my interested piqued by hundreds of different topics and libraries even vaguely relating to web development. I find myself reading articles on everything from CSS to TCP to Ruby testing. Whilst I find interest in everything I read, I feel like I should try and be (at least a little bit) more focused on things that affect my day to day work. How do you manage this?
