I won't link to the awesome guitar solo by Lil' Wayne, but it is interesting to see that guitars can be found on stages for rap and pop bands. It just isn't a front-and-center instrument anymore, but it still looks better than a piano on stage.

I'm also of the opinion that if you are learning music to become a star, you aren't learning for the right reasons. If you become good enough to make money at it, that's awesome, but I don't know many musicians that do earn any money.

When I was a teenager in the 90's I got into guitar thanks to fantasies of being a famous musician (but also more attainable ones of attracting the interest of girls). I never had the time, resources, or motivation to become anything close to professional but over the years I'm still quite glad I took it up.

I don't practice often but as an adult I have a little disposable income to pay for a couple of guitars and an amp. I even picked up a cheap travel electric guitar with a built-in amp/speaker which is honestly awesome for noodling around over top of someone playing acoustic around a campfire or some such.

Not really trying to make any point I guess. I had vague dreams of fame and fortune but found that over time, it was still pretty rewarding to be able to play something even if I don't give it as much of my time as I might. It's a creative outlet, it can be a way to relax, and you know...occasionally, girls still dig it :)
