So basically hobbies and travel... My problem - my hobbies is what my friends see as a "work" (and I identify it as a work as well). Traveling is alright (although it is plenty of work with whole family, which includes two kiddos) - but it gets old rather quickly (again, perhaps part of it the fact that it is family traveling, so entertaiment options are rather limited)... Perhaps kiddos get old enough I might re-discover traveling as a way to relax, but until then doing nothing makes me more anxious than just keep working. And these self-help/productivity book are just tools, just like "c# for dummies" books.
