A friend of mine said that he was a cynic. I had told him that he was giving up too easily. In this situation, the worst case outcome was rejection, which logically speaking, was equivalent to not trying in the first place.
I want to say, "No, you aren't cynical, you are X," or "No, you aren't a cynic, you are a(n) X."
The closest I can come up with is unmotivated or intimidated.
What word describes a person who gives up too easily?
