I would like to agree with this and hope this is true. As Steve Jobs once said he would much rather be considered as builder rather than trader. And so building part of entrepreneurship is more like an art. As unpredictable and challenging starting up a company is, I would like to think that it is the art aspect of it that makes it somewhat fun as well. As difficult, unpredictable & dangerous doing a startup may be, there must be this fun aspect of it(which is more artistic) that makes it fulfilling. Else it will be just like another exam(to be passed, graded to be acquired).
