Tim Berners-Lee says in this TED talk how his frustration over locked potential gave birth to the HTTP and HTML. If you for a second overlook the fact that it is HTTP and HTML he is talking about. It is very interesting to listen how he, so different to everyone else, decides to solve this problem. Most of the us would just accept the problem and put more man-hours to it rather than even thinking of solving it!
I am impressed by people that are not easily scared by the complexity of problems or the amount of work and energy needed to solve them. From my experience, if you are not intimidated by the amount of commitment and work a problem requires you will find that your fears far exceeds the actual work and commitment required.
Take the time to look through this great TED talk!
