I've been considering this myself for a while. What's the best way for a nerd with no sales knowledge (well, i can sell things off a webpage just fine, at least if they are cheaper than the competition, but that's a rather different thing.) to get into sales?

should I leverage my existing skills and get a sales or pre-sales Engineer job selling some overpriced "enterprise storage" or network kit? or should I show up at a used car dealership and ask for a job?

I bet I could at least get past the interview; I'm tall and white and can fake confidence fairly well for a nerd. I don't know how long I'd last on the used car lot, though.
