The first step in preparing for the day you quit your job is to plan out the launch of your business (or, in Nhuri’s case, its expansion), thinking through everything from the type of location you want for your office to how you want your product to look on store shelves. You need to work out as many of the bugs in your plan as you can ahead of time -- while keeping an eye on the clock. If you take too long, the circumstances might change, altering markets so that you could miss your opening.
