Success as in; it was worth your time, you collected all the money back you put in, and made or continue to make a profit.. not just pennies. I think it would be interesting to hear what % of people's projects they consider a success, and would give people a more realistic idea on what to expect. For me I'd consider about 60% of my projects that I pull the trigger on successful, a little more than half. I think that's high but I spend probably more time than most researching before I jump into anything and would probably make more money if I took more risks, but I hate failing. When I was first starting out that percent was probably around 20%. I also spend huge amounts of time researching potential ideas that I never end up giving a real try, and I know that's a waste.
