This is perceived as an easy job that anyone could start up with very small outlay, just perseverance and a couple of friends or relatives as customers. A bit of time and physical work later and you have yourself a self-starter business. The trick comes with the ability to endure, the foresight to try and maximise your work and output and not getting caught peeing in your customers grids.
If you want or need to be a captain of industry, then you probably could. Just keep buying rounds, refining work, employing decent staff and hey presto! You're a small business owner and might stand a chance of getting on the committee of your local golf club.
Or you could just work smart, enjoy meeting people and be happy in your own skin earning what you choose to earn. Horses for courses (apologies for the cliché).
