For example, consider hiring a personal chef (not as expensive as you might think)

Probably quite expensive compared to the monthly budget of a student–I can only work on weekends–but something to think about when I graduate. I have this weird aversion to doing things like that, which I think is based on the association with 'stuff that snobby rich people do."

I already have a very efficient cooking routine–I probably spend an hour on cooking once every four days, to make a large pot of something I can put in waterproof glass Tupperwares and take to work or school, and then I spend another 10 minutes a day heating up food to eat it, etc, and packing my lunchbag for that day. I know how to shop cheaply and I spend well under $200 a month on all food-related expenses. I'm guessing a personal chef is more expensive than that. Plus I like cooking–it's therapeutic when I'm stressed.

I will very likely hire someone to clean my house for me once I have a house, though–I hate cleaning. Right now my apartment just isn't very clean. And it was someone on LW who gave me the idea of hiring a cleaning lady to trade money for time. I had the same snobb-rich-people aversion, but convinced myself to overcome it.

You actually don't need to do that much. Read "4-hour body" and look into high intensity interval training (e.g. tabata sprints).

Sounds efficient. Also doesn't sound like much fun. I'm not a fan of sprints, mostly because I've always done exercise with a group (swim team a long time ago, now taekwondo), and I likely have a genetic tendency towards having lots of slow-twitch muscle fibres, and great endurance, but fewer fast-twitch muscles, therefore awful sprinting ability. Sprints and high-intensity stuff in general is now associated, in my mind, with me being the slowest one, whereas I used to overtake even much faster swimmers in long endurance sets.

That's not an excuse not to look into it, though... I'll read the book and see if there's anything I would find bearable to do regularly. I need to re-motivate myself in this area, anyway; if I don't exercise I get cranky and emotional, so I have to exercise, but most of the time I don't like it and it saps my motivation.
