Tendency to be Negative

The other day I came across someone who wrote this in part of their dating profile:

I have a tendency of sometimes being quite negative, this is something I am working on slowly, I try to accept people in spite of the things that I dislike about them as I'm sure they do for me for which I am deeply grateful.

Now, considering how many people are available to pick from in the dating world, I would probably really stay clear of someone who not only recognises themselves as negative (even if they are improving they still identify as that) and who tends to look at what they dislike in others first.
