"Everyone always talks about entrepreneurship like a marathon, that it is a long haul that you have to push through. I say it’s more like ‘parkour’ where you jump from one building top to another. You always need to shift and adapt; and if you do it enough, you begin to anticipate different situations. It’s never going to be a straight path to something and you need to know when something is not working. There is a difference between being stubborn, and knowing when its not working in order to approach it differently." (Source)
