Good idea, bad idea

Do you remember watching Animaniacs as a kid?
I was always amused by the "good idea, bad idea" sketches. You know, like:
Good Idea: Playing the piccolo in a marching band.
Bad Idea: Playing the piano in a marching band.
Good Idea: Doing your own yard work.
Bad Idea: Doing your own dental work.

Well, we are starting a side business with a friend.
Here's our list of business ideas we think are a bad idea:
--A petting zoo with large predatory cats.
--"Super Skivvies" adult superhero-themed underwear.
--House flipping in this economy.
--Marketing "I heart Al Gore" bumper stickers in Texas or Utah.

So, after tabling those propositions, we decided to develop an on-line prep course for students taking the Law School Admissions Test (LSAT).
After law school, I taught LSAT classes for a large test prep company. There were strategies I thought were helpful & others I plugged with less genuine enthusiasm. I'm excited about the prospect of developing a course that is individualized, flexible, effective, and with any luck, somewhat profitable. We met with the friend we are teaming up with this week. Although this will be a tremendous amount of work, we are excited about the opportunity.

Good idea?
