It blows my mind how people start such big businesses. You must build an airport, hire stuff, buy planes, meet many legal requirements and so on, all costing tens of millions of dollars, and on top of that, it must be profitable. This gives some insight, but still it's terryfing. I feel so small.
When I stood there under the Eiffel Tower, I felt like I never had a grand thought in my life. To think that massive undertaking started in someone's head is just humbling.
So I feel you. I feel so small.
