To create a business, find someone who needs something done. Then, find someone who will do that thing well.
Charge the first person and use that money to pay the second person.
It can become much more complicated than that, but this is the core of a business.
I wrote about this on January 1st this year, and my understanding has expanded since then. Rather than just finding customers and doing work for them, you open up an entire world of possibilities by outsourcing that work to other people.
