Success Through Giving

I have a friend that I met in one of my acting classes. We are both trying to achieve the same dream. I have studied about the seven spiritual laws of success as well as creating affluence, and I do believe that by helping others achieve their successes, success also comes to a person. I’ve only been studying about the ego and the laws of success for a few months, and some days I have a lot of trouble, while others I feel very confident; however, recently I’ve felt that as much as I’ve tried to help my friend, through making important contacts and connections, she seems to not help me in return, but to use my contacts to help herself only (one instance when I was engaged in a conversation she interrupted to promote herself). I know this stems from my ego and hers, and I truly do like her as a friend, but I am not sure how to deal with the situation.
