I am absolutely convinced that most people don't live out of a place of passion, and are therefore living unsatisfied lives. You can hardly blame them, in an post industrial world, it's much easier to fall in and get by with minimum resistance. There are many obstacles to living out of a place of passion. It's not practical, it's not what people expect of you, it might not make you rich and famous, it's scary and too new agy of an idea. And yet deep inside, most of us feel a deep need to live like that.
I just had lunch with a good friend, a remarkable professional, who was feeling the need to change things because his work, although well paid lacked significance and passion. Very few people even get to that place, as to question the status quo. Because, what if the questioning leads to a need to change things? Scary.
