Am I narccistic or just proud of what I have accomplished?

I have recently had a very close family member tell me that they do not like who I have become and that I am a selfish, self-absorbed, self-centered person and my life revolves around myself and no one else. And after alot of thought on this, the conclusion that I have come down to is that I have many activities that I am involved in ,and I am a person that strives to be successful. So I am constantly trying to figure out ways of how to do things better, and how to become better at what I am involved in. As well as how to learn new things, and increase the talents that I am able to do. This is my life, so it's all that I know TO be. When I talk to people, I admit that I enjoy telling them things that I know how to do, and that I have accomplished, and if they ask more detail about it, I will glady inform. I have never seen this as being self absorbed, just proud of the accomplishments that I have made and the talents I am blessed with to do this. But since this family member has mentioned this, it has really caused me to reflect and the more that I have researched the more that I feel I fall under the catagory of narcissistic disorder. But I am just curious of how you set the boundries?? Any answers, help or advice?
