The song says it all - accentuate the positive, eliminate the negative.
As a chronically negative person I find this very difficult. It is funny, I have no problem telling myself a hundred times a day how horrible I am, but when I try to tell myself I'm good at something, it sounds false. I think the negative 'affirmations' only sound genuine because they are so familiar.
Anyway, who wants to have anything to do with a sorry sack? Putting myself down isn't going to get me anywhere. I know I said I wasn't going to make any New Year's resolutions, and I'm not, but I am going to try and be more positive about things.
What do you do to keep positive, or do you think looking on the bright side is overrated?
