It depends on the project really. I've been doing the nights/weekends thing for a while now for a new startup of mine and I couldn't be happier. Could I launch quicker if I quit my job? Absolutely. Is it necessary? Nope. If you're happy with your job and enjoy receiving a steady income, keep your job, work on the project until you get a real gauge of what you want to put into it and how quickly you want to launch, then make a decision then. My personal plan is to stick with the job, work on the project until I'm ready to launch, then to see in a small test market what the viability and money potential really is. Then, if I think it looks good, I'll quit and dedicate more time. I'm obviously biased, but it's absolutely possible to build a product in your free time.
