Twelve lessons, four stages. Each lesson is short, stands on its own, and ends with one number: yours. You enter it, it saves, and the next lesson picks it up where you left it.
By the end you have twelve numbers that describe your business more honestly than any profit and loss: what it costs to stay open, what a bid has to carry, what your last job really paid, how long your cash is gone, what your debt costs you, what you pay yourself, what a field day produces, what a hire really costs, how many hours only you can do, what you can invest every month, what your first project of your own costs, and the number that makes the work optional.
