Some people remember things very well and learn from their mistakes. However, I am not one of those people. I know what I did wrong, but it's remembering what I did that is the problem. I forget so easily that I will make the same mistakes over, and over, and over again. This proves a greater challenge during any memory test or something like that because I will make the same mistake several times.
This doesn't make me a poor learner, it just makes me bad at remembering things ... which is kind of the same thing. I can normally only remember the things that interest me.
