Meg-A Music Toronto knows how you can make it in the music business.  Check out their “Tips for Indies” page – they’ve got some valid points:

Network. All the other performers and musicians in your area are trying to develop their own industry and venue contacts. Share yours and get theirs—as a group you can move forward more quickly than as an individual. Try to develop an atmosphere of cooperation that extends across the boundaries of musical style—being a bigot in your own genre only limits your opportunities.

Practice. Even a pro has trouble overcoming a screw-up when they are obviously unprepared. A little mistake is common, and fine. Constantly messing up because you're not ready, is not.

Play live. A live performance is worth ten rehearsals. If you don't have paid bookings, play for free.
