When it comes to success, I believe that two intertwined behaviours are critical. The first is always being humble enough to be a student, to learn from every experience and every person we meet. The second is taking responsibility for helping others find their own success. I do believe that finding both happiness and success is a path we walk together.
On a practical level, success achieved through going it alone and without help or any form of cooperation is, in my opinion, fool hardy and will be short lived. Long term success comes from helping others and allowing others to help us. We have to trust that others will execute their part well and we have to prove that we can execute our part well also. Success and cooperation are inseparable.
