Maybe you do not need a plan. Maybe sometimes you should just be random. Do not plan anything, just go out into the wide world and see what happens. Who will you meet? What will you discover?
Go to a library. You know the giant buildings with lots of books. A large university library is the best, with lots of stacks. Just bounce around with no purpose until you find something fascinating and dive in. Spend the whole day, learning something new.
Get in the car and head down a highway and stop at anything remotely interesting. Talk to people while you do so.
Just start calling random people in your business world with no agenda and see what you uncover.
Be random every once and awhile.
