I'm an INTP (I have no doubt about this) and a few years, I might end up taking over ownership of a family light manufacturing business with about $2 million in sales and about 15 employees. I have a background in accounting already though I haven't finished school yet. Don't know how that would go, but my dad, the current boss, is an ENFP who is bored of the business and mostly ignores it in favor of his organic farm, which actually interests him. I understand the business pretty well having worked there in the past. I posed the idea of buying the business from him (he would finance it) and he tentatively accepted(!), though with the understanding that it'd be after I finish school. He knows selling it to an outsider would lead to its dismemberment, and he's quickly getting toward retirement age. The business is currently actually run on a day-to-day basis in a sort of egalitarian fashion by the IxFP sales manager, ESTJ production manager, and INTP bookkeeper (a friend of mine).
I don't know if I would be a good leader, but no other move would lead to me making so much money so soon (it will probably be about at the six-figure mark to twice that, depending on the year) without having to report to a strict, authoritarian boss. As long as I can segregate the company's liabilities from my own personal savings, I should be golden for a while.
