The Dissatisfaction Thing

As long as you've got that dissatisfaction, there's always something to fix or see as an opportunity. Even if your life improves drastically in a couple of years, you'll probably be equally dissatisfied. I never like actually found it useful, but unlike link lists, which I never used even in a tangential kind of way. It would have been really nice if they had gone all the way with assembly language and just gone down the whole thing so you like really understand the whole thing.
