Calculate how much runway you need to sustain building your own product with zero income for say, 2 years. Either (1) save till you have enough then stop taking client projects* or (2) Narrow down the scope of your product so you can work on it part time. * Even when you are working full time on your project, it doesn't hurt to do some consultancy at higher rates to keep your contacts warm as well as building a stronger runway.
