When you grow up in the bottom 10% of the nation's income scale, there's a natural push to save money on anything you possibly can.
I was one of those kids, and learned from an early age to conserve whenever possible. (my mom even made a living for awhile writing books about saving money).
And there's a good reason why musicians should conserve as much resources as possible:
?It leaves more money for you to use on the things that really matter.
?It frees up more time, since you're not buying/using as much.
?It's just the right thing to do.
Saving the environment and advancing your career- the best combination ever.
