I didn't say it made them better musicians because they can do maths and english, etc, but we were talking about musicians in a specific context; folk scene, self employed, and "deserving recognition".

I mean, personally, I think I'm more beautiful than Jordan, and more suitable to being a model but do I have the drive, ambition, care, sense and intelligence to make it all come together, to pull it off? No. It doesn't need to be pointed out that the more effort you put in, the more successful you will become, unless you're very lucky.

If you want to be a good musician= practice music everyday, love your instrument, listen carefully, study hard, etc.

If you want to be a successful musician who earns a decent living and gets some recognition= do all of the above, learn about business, work your way through the crappy gigs, the crappy people, the crappy money, do your maths, english, etc...
