I post whatever I find interesting and occasionally throw in one of the articles I worked on. If people find it interesting or useful, great, if not, that's okay too.
Still, I think there's some utility for self-help stuff. If you spend 30 minutes reading about how to be more effective, if the book is good, it can actually affect behavior, at least in the short term.
Others have already offered the more obvious advice, so I'll just add something a bit weird: I've started taking swing dancing classes and it's good fun. I meet people (some of which are women!) and it takes me out of my head. It's good active sort of relaxation.
I've noticed that a lot of programmers are into swing dancing, about 1 in 2 men I talk to at social dancing are in software in some way.
Okay, this might get downvoted, but posts like this are exactly why my co-founder wrote a big series on addiction in general and Internet addiction in particular.
