My Brother runs a lure company. I asked him about this and he me this answer. What defines making a living? It's easy to find out.. Find out how much profit you make per lure (minus taxes, costs, employee labor etc etc). Say profit is $5. Say 50,000 is a living. 50,000/$5 = 10,000 lures. First question is 50,000 considered a living for you? If not change the formula. 2nd question can you market enough to sell 10,000 lures. second question can you make 10,000 lures? This is just a reverse way to look at things.
