One of my very close friends is visiting from Florida this weekend. I took him to the Museum of Flight today. It was very inspiring to see what William Boeing did. In addition to the Wright brothers, we owe the evolution of the global trade to William Boeing. He was a Yale dropout who moved to Seattle to make money when he was 21. He did make money in lumber trade. He was a millionaire at the age of 27. In 1909, he came across seaplanes and was fascinated by them. Furthermore, he thought that they could be made better. See William's biography at http://en.wikipedia.org/wiki/William_E._Boeing. What was most amazing at the museum was the speed of technical advances in those days. After the first flight in 1903 by Right brothers, the aviation industry involved very fast. The commercial flights began in 1928, less than 25 years after the 12 second long flight. I am amazed how the technology progressed so fast without the communication channels (Internet, TV, etc.) which are available today and without computers.
Pursue your passion, everything else will follow.
