12 years into my graveyard of side projects and making a modest income, nothing has ever "taken off", but I have survived. I yearn to be "pulled" by the market inextricably, but that is unlikely. The reality is almost every business (and I mean almost every one) is "pushed" up the hill, interminably, like Sisyphus. Even my most successful clients never feel "ahead". Something always breaks in the business model, given enough time.
