Entrepreneurship requires risk at 100% level – the dare to succeed even if it means ultimate death. It sounds like life itself.
Why do we do what we do if we know that we are born, live, then die. Seems that the joy of experience itself is point of the ride.
If we are limited by rationalities only, or reasons to act in a certain direction, then we're surly to miss the greater surprise.
While the world spends 80% of its time planning for success, what they encounter is 80% of surprise for things unplanned.
Let it be and apply what you learn along the path of your experience in every moment.
