Do I really need a business plan?

Having a business plan is one of those important prerequisites for starting a business that they teach in business school - Right?    But do you really need one? What's the best way to do a business plan? Is there a Chill and Prosper way?   As someone who was never really good at assignments, writing a business plan always felt like boring homework. Plus, my ADHD and procrastination meant I never got around to it.    Maybe you're like me and don't want to take the time to plan because you're too busy taking action.   Please don't procrastinate starting your business because you're waiting for the perfect plan.  It's totally fine not to have a business plan, but you do need to have a rough idea of where you're going, so I've got some alternatives for you.
