If there is a niche, need or demand in your hobby, then it can be monetized. Though it depends on your commitment too. In both of these stories, those who succeeded had quite their employment to be able to make time for the creation of their business, or passion into their hobby. Anyone can give that a shot, though it is a high risk pathway and only 1/10 will dare to take the risk, and only another 1/10 will succeed after taking that pathway.
Just because a passion can be turned into a business, it doesn't mean that a business should be treated like a hobby or passion. Plans and sacrifices must be made before starting the journey and to ensure its success. Otherwise the failure might destroy the taste of the passion (and your wallet).
There's no denying the allure of turning a hobby into a moneymaking enterprise. But your success rate numbers are grim; they reflect the hard truth of starting a business. This is a road less traveled, for sure. But could there be elements beyond effort and time that make a difference? Perhaps external economic conditions, market saturation, timing, competition, a distinctive value proposition, and other factors all play a role in deciding the eventual fate of these enterprises.
Agreed to all. I'd say 100:1, 100 being attempts, 1 being successful in the venture...maybe worse....but what is life without risk?
As for external conditions, this is probably more so the reason for failure than it is on the person. If those external factors weren't factors and it all came down to the persons' effort and hunger, I'd say the odds of success would go from 100:1 to 10:1, maybe even 5:1 or 3:1. There are always external factors however, that's a part of what should be factored into the plan that should be created before going ahead and starting a business.
Furthermore, I have to politely disagree on one point: the assumption that a business founded on a passion can't be treated like a hobby. Even while running a business requires a methodical and analytical approach, wouldn't you agree that the hallmark of successful passion-based businesses is that they keep an element of enthusiasm akin to a hobby? Finding that sweet spot might be difficult.
Maybe I worded what I was trying to say incorrectly. I meant that the same general approach to a hobby (spontaneous, leisure, non disciplined etc) or a hobby-like passion can't be turned into a business in the same way, exactly for the reasons that you said (requires methodical and analytical approach). While I see what you are saying with enthusiasm being the hallmark of a passion, that doesn't mean that the same enthusiasm would go toward the new mundane tasks that a business would require to succeed in the near and long term. No doubt that the enthusiasm will help, and no one should really start or run a business without a level of enthusiasm, though I wouldn't say that this is enough to improvise or overlook the complexities and mundane tasks that are involved in running a business.
