A Quote from Albert Einstein I like is: "Imagination is More Important than Knowledge", (BTW you can find an other interesting quote from Einstein on the leftside of this blog, if you scroll down.)
'A lot of Internet Millionaires really thrive on Passion', sometimes created their business as a student in a basement, than created explosive exponentional growth that wouldn't have occured when looked at it logically. Usually in Business it would be logical to aim for an annual growth of 3 or perhaps 6 % and not an explosive growth like for example 500% or more! Logic would only have been in your way, because based on 'Normal Business Knowledge' it would have been madness to believe such things possible. Lucky for them they wheren't 'Reasonable' or 'Logical' but Passionate and Imaginative.
