Lol, my first thought when I read the title was setting up a business entity...
Always feel free to jam a bit. If you forget to have fun, you won't learn nearly as much as you would otherwise, and are far more likely to burn out or just give up on it. I've been guilty of this mistake more than once in my life.
You'll be better off taking one lesson "out of order" and otherwise sticking to the program than you will just blindly following the practice/lesson schedule and hating it. Just be prepared to "relearn" that lesson or technique when it comes up again normally.
