How do you pick names for your Sims?

I spend a ridiculous amount of effort into choosing the right names for my sims. I've had a notebook since TS1 that I've kept all my favourite names in (and some random ones), they're organised into alphabetical order, and then I have sections for 'theme' names, like from particular countries, or sports stars, or now Hawaiian type names since Sulani… and then I go through and choose the one that sounds right for my new sim. I used to generally pick similar names, but I've started trying to pick names that I would never normally choose, and I'm really liking that. It's a bit of a weird obsession of mine choosing names, but it keeps me happy ;)
