I dont have a specific number but am sure it would surpass 75. The way I see it there are things I could be spending my money on that would give me far less enjoyment. I love my hobby. I share it with my wife and kids. They love it too. I am blessed that I have the disposable income to allow this fairly expensive hobby. Also if furtunes ever changed I have a significant amount of easily liquidated assets to help in that circumstance.
Half the country hates my business, the other half my hobby.
