Assassination or Negligent Homicide

I said something yesterday that has me thinking. I told someone that I once had a dream and I was told I would not be able to ever achieve my dream. I went on to explain that I had accepted their words and accepted that I would not be able to achieve my dream. REALLY! I did that. Now, I am wondering, did I sell out on my dream? Did I give up with no fight? Isn't that contrary to who I am striving to be? Did I let that person assassinate my dream or did it die of my negligence? I'm going to have to think about this one some more.
