Well, if I could make a decent living out of being a pro folk singer, I'd certainly be proud of it, and I tip my hat to those that do! But I realise it's not as exciting as it might seem to others, as any musician who has spent significant amounts of time on tour will tell you. As weelittledrummer said, it helps if you don't have too much of a home life (family etc.) to worry about.

I'm realistic enough to know I'll never be able to go full-time professional, partly because I don't want it badly enough. I guess I'm happy playing and singing for enjoyment (and the occasional few quid if I'm lucky), with the chance to meet like-minded folk wherever I go, to be privileged to chat to my heroes occasionally, etc., etc.
What I would like would be a day job that would allow me to take more time off to indulge in what I regard as a major hobby rather than a potential full-time living. Maybe when I finally retire... ;-)
