People who drink coffee: why did you start?

I don’t drink coffee and I’ve never wanted to, but that’s obviously ~not normal~, so I’m curious why most people do start drinking it.

Additional question: People who don’t drink coffee, why?

For me, it’s because, as a child, I was incredibly cranky, and as soon as caffeine-free Coke was introduced, Mom had me start drinking that, and, hey, I got a lot less crabby, so that made me want to avoid caffeine. I also never really cared for the smell of coffee, either, so had absolutely no interest in drinking even decaf.

(and yes I am very aware that “it makes me feel better” and “love the way it smells” are top answers in why people do drink it XD)
