If you are up for playing, why not play with sales and marketing? Playing isn't limited to tech. Grab a pencil from your drawer and try to get someone to buy it. Just like with those little low stakes tech projects, as you keep prodding at it to get it to work, you are bound to learn something.

And if you truly have nothing left to learn about sales and marketing, well, then you will have at least learned that the problem you have isn't what you are currently suspecting.
