Sounds like you missed the word "moonlighting" in the post you're responding to.
You keep your day job writing software and do your entrepreneuring on nights and weekends. Try things out until one of them is matching your day job's income, then quit and go full time.
That's what I did. And come to think of it, it's yet another factor to throw into that Perfect Storm I mentioned above, because you can't really moonlight out a brick and mortar store while keeping your day job at another one.
