The million dollar question, I'll let you know if I find the answer!

I wouldn't underestimate the luck part though even if you do come up with a brilliant well executed idea.

I've acquaintances who spent years trying to commercialise side projects that have eventually come to nothing. A lot of disappointment but I guess you've got to put the hours in and try something to even have a chance.

Personally always thought the idea of something low key with a continuous income stream sounded the most realistic, as others in this thread allude to. But you still need the idea, the execution and the luck.
