If there’s one thing I’ve learned so far it’s that there are very few moments where the correct answer to “should I get a massage?” is “No.” This place is good, and cheap.
Actually, I’ve learned plenty of things. Pop music can sometimes change the world, but mostly doesn’t. The fact that it mostly doesn’t is not important. Total, clean separation of programming logic and presentation in a template system is not possible, partly because a template system is an interface between programming logic and presentation. Almost all books considered classics are worth reading, or at least dipping into.
And that’s just four. I could go on, but the massage has blissed me out too much.
And, really, everything changes the world, when you think about it.
