The reason for this question is complex and the answer is equally complex.
First, as entreprenuers, we are weird. It is not normal to work for yourself. It is not normal to spend the money that we do on practical (rather than fomal) education. It is not normal to focus on peronal growth and development.
Second, we are in "sales." Sales and marketing scares alot of people. it creats images of the slick talking salesman or the crafty marketing specialist that gets people to do thing that are not in their best interest.
Third, they listen to alot of naysayers and always ask what if it goes wrong
Fourth, they are resistant to change. Getting into this business is a big change for anyone.
Fifth, they are unwilling to learn. To get good at something, you must first suck at it. People dont like doing things that they suck at.
Sixth, We need to realize that not everyone thinks like we do. One of the most common assumptions that we have is that other think like we do. That is why people can get so heated in debating religion, politics or sports. What seems obvious to us just isnt in their paradigm of the world
So hang out with weird people and when an outsider looks in with curriosity, welcome them in and help them out. Because to court this group takes courage. and that spark must be nurtured.
