I think that there are seasonal trends in personality and aptitudes and I believe that some of these have been verified scientifically. However I don't believe in the reasons astrology gives to these trends. They are just a story we tell to explain these things.

I also think that there is something of the self fullfilling prophesy in astrology. Because we know so much about what our star sign is supposed to be like, we emphasis those parts of our personality that fit in with the model until we start to become the model.
