Once you do decide to quit, make sure you leave in the right way. You’ve made a commitment, so follow through and try to finish as much of what you started as possible. Find a natural breakpoint in your project—the next big milestone—and aim to leave then. The longer you’re at a company, and the higher up you are, the longer it will take to transition out. Individual contributors can usually give a few weeks to a couple months of notice. CEOs may need a year or more.
