Think back to the days before you started your business, when you were working for a boss. Chances are you were rewarded for your hard work with a regular salary. It may not have always been the same amount, but it came through like clockwork. And for the next week, month or however often you got paid, you'd do your best to make it last.
But now you are the boss, and so you don't need to be restricted to a set salary, do you? You can simply draw money out of the business whenever you need it, right?
