From “Work-Life Boundaries for the Passionate Worker“:

The only problem with being super-passionate about your work life is that work can take over your whole life. That’s especially so for web workers since near-ubiquitous connectivity means you can almost always tweak that website, write that blog post, or code that next feature no matter where you are or what time it is.
