If you're like me, you (a) have barely enough money to make it to your 40th birthday, and (b) spend roughly 23 hours a day trying to figure out how to become independently wealthy, hopefully without having to try very hard. You rack your brain trying to find something special within your skillset that would yield a product for which people would pay handsomely. Handsomely enough to at least retire before you own a colostomy bag. Handsomely enough to at least make sure your kids college alma mater doesn't contain the word "Community" in it. Your head hurts from concocting business plans in your mind, and maybe even transcribing them on the proverbial cocktail napkin.
And then you drive through Mississippi, see a billboard, and realize that the best business plans sometimes are beautiful in their simplicity, and you lament "Why didn't I think of that?"....
BUSINESS PLAN -- Cheap beer. Cheap tobacco. Without leaving your car.
