Ben Nadel described it perfectly:
I have been using jQuery for a while now and the high has still not worn off. Even now, after I know what to expect, I find myself stopping in the middle of event wiring and thinking to myself, “This is so darn easy!” How is it possible that I'm still surprised as to how little jQuery code is required to make some really awesome stuff. It's just bananas. When I code in jQuery I am overwhelmed with this feeling that things are just falling into place. It's not like an adrenaline rush or anything – I'm trying to think of how to explain it… it's like when you think of something really funny to say and you're just waiting for your turn in the conversation and this feeling of anticipation builds inside of you; it's like that; it's like you have this anticipation of greatness. Now, not to say that the outcome of the coding will actually be great, but that the use of jQuery is so empowering that you kind of just assume that greatness will ensue.
Just a little stream of consciousness for you.
