This is the 'best' way, absolutely, but it's not the easiest and it's tricky if you need a regular income.
But even if you try and it doesn't work out 100%, you still learn a ton.
Rob has a new book out, by the way, "The SaaS Playbook". Haven't read it yet, so not sure how it is, but "Start Small, Stay Small" is one of the best business books I've ever read because he went out on a limb with real, practical advice rather than handwavy BS. That means it's a bit dated now, but probably still worth a quick read.
