I don't think this advice applies to every type of business. Particularly service-oriented startups that are able to land paying clients right from the beginning.

I will agree though that working at a company that isn't financially stable is not a good place for someone who needs financial stability. Imagine your boss telling you that your next paycheck will only be half - or they can't pay it at all, but you'll get paid back later. Imagine that happening occasionally throughout the year. Add to that a constant, looming feeling that your company could go out of business any day even though you love working there. If those kinds of things upset or stress you out then a startup probably isn't a good place to work.
