Depends what you define as "success". Probably my wording was not the best. Our business is extremely successful, but in different ways that most people define success.
We don't have a huge monetary success and no one is going to buy our company for multiple millions, but we have a lot of freedom, cool people and pretty fun adventures together without having to worry about financials either as long as don't start driving Lamborghinis ;-)
That said, the financials need to be good to support the lifestyle part. But if you live smart (not wasting money on a lot of things you probably don't need anyway) you get pretty far.
