If I played for a living, I'd've starved to death decades ago. I play guitar because it's fun, because it's a vital form of non-verbal expression for someone who makes his living with words and because it's a serious buzz to be in a good band with nice people (as I'm currently fortunate enough to be) and combine the noise I make with the noises other people make to create music which, most of the time, other people seem to enjoy almost as much as we do. After having been in bands more or less continually between 1977 and 1995, I took a dozen-year break and didn't realise, until i was back in a band again, how much I'd missed it. Towards the end of that break, i started playing solo, then met up with a kindred soul in the form of harpmeister Buffalo Bill Smith ... and then we expanded what we did as a duo by adding a rhythm section and morphing into the first line-up of Crosstown Lightnin', a four-piece blues band ... plus jamming with other bands on harmonica or guitar and doing (very occasional) sessions.
'Stardom' isn't the issue. Neither is money, beyond a desire to at least break even. It's about playing because I love it, and because it adds something to my life which I can't get from anything else.
