Great advice, though I'd make explicit a single caveat: work at least a year or two at a reputable tech company after college. It's actually a more effective environment for networking (it seems every person in tech wants to strike out on their own these days), you can build up a cash base to extend your personal runway, and most importantly you'll have a more coherent and believable narrative about the direction you're taking, in case you ever need to be employed again.

Plus knowing how abysmal the corp life is will keep you driven ;)
