Lifehackers series "This Is How I Work" is a real favorite of mine. In the series, you get a glimpse of how skilled professionals, mostly writers and individuals with a strong online presence, manage their workdays and what type of resources they're using to establishing a nice workflow. And another important thing – most of them don't neglect sleep and exercise, which for me was a happy discovery.
