A one man consultancy operation is as much entrepreneurism as serving billions of users world wide.
I think we have this misconception that success mean you need to have hockey stick growth on bunch of metrics, anD that you must make your investors 10x return on their investments.
Fundamentally the wrong approach. As an entrepreneur I don't strive to "make money", I strive to learn, adapt, and survive. Money and success depends solely on how well I can iterate those three things.
