As someone who has never been well organized, how can I successfully start using a planner?

Trying to get my business off of the ground, I'm realizing that I need to be better organized. However, my entire life I have never been any bit 'type-A'. As a child, my desk, backpack, locker, you name it, were always a disaster. As an adult, my desk looks like a catastrophe. My computer has 11 tabs open (honestly miraculously few), and my phone, ∞, my clean clothes get dewrinkled as needed from the heap in my wardrobe. I laugh at my partner for deleting emails. As a child, I would get detentions for refusing to fill out my school planner.All that being said. Lately, (within the hour) it has hit me that if I am to have any success as a business owner, and hopefully boss/CEO in the near future, I am going to have to buckle down and start planning out tasks, goals, and obligations, as well as marking important things on a calendar or planner to make sure they get done on time, or at all.How can someone like me, that has always lived in chaos, flown by the seat of my pants, and looks at using a planner like making the bed (time consuming, monotonous, and pointless)... how can someone like me start using a planner, calendar, or some kind of organizing app?
