The Success Rate in Business as an Entrepreneur

I have started or helped start about six businesses in my life. Only one out of six was a big success, that's effortless English. The other three I tried were either very, very small successes or not successful at all. So what's my success rate? 50%. If we count, if we count the one that was small, that still made some money, we count that as a success. Even though I did eventually have to close it, even though I could not live on that, it's still it made money was a profitable.
