You don't sound like you have much to lose, but don't forget that most the people here have a bias towards starting startups vs keeping a steady comfortable position. Even if you do have a good idea, I think you should only really do your own startup if you think you are the type of person who can get it done without a lot of help or if you have confidence that you'll be able to get the help you need. You might want to try and find people who can help you (potential customers, investors, partners, etc) before making a final decision. If you find yourself having trouble getting people to help you early on, that should tell you something.
