Established Piano Shop Owner. Salary: $55,000 

Your shop has been around for a while and you're doing pretty well. You're the go-to musical instrument stop because you've integrated yourself into the community with lessons and recitals.

Owner of Piano Shop with Multiple Locations. Salary: $87,000 

You've opened up a second location, and you never could have guessed that selling pianos could lead to such a luxurious lifestyle. You basically just spend a couple of hours a day delegating tasks and then sit back, relax, and watch the money roll in.

Small Piano Shop Collection. Salary: $150,000

After all that hard work at the beginning, you can finally start taking more personal days...without sacrificing the excellent restaurant meal that you can definitely afford.
