If you think you have an idea worth pursuing, work on it on the side while keeping your "day job". If it takes off, quit your job once you can replace your income with the side work. Also, as a warning - double check your intellectual property agreement with your employer. Some employers will draft them so as to read that ANY idea you come up with (either related to their business or not, just because you work for them) is automagically THEIR intellectual property. Needless to say, this not a good position for your new brilliant start-up to be in.
