I'm taking 30x500 from Amy Hoy and Alex Hillman. They are in patio11's orbit. It's an expensive class and would only be worth it if you are really willing to commit. They have some other less expensive products (Year of Hustle, Just F$&*% Ship) that you can use to dip your toe into their methodology. Look up their blog "Stacking the Bricks". Not affiliated in any way, just a fan and appreciative customer.
