I was contemplating last night the issue of outgrowing one's dreams.  Not that you outgrow them and they are no longer your dreams, but that your physical growth - either in size or age - makes your dreams no longer plausible for you.  For example: I have always loved horses. When I was very young, I wanted a job that let me ride horses for a living. I wanted to be a horse jockey.  Then I grew to be 5'11", and clearly there is no way that specific dream could be a reality.  Fortunately, it was also a dream I outgrew in that I no longer wanted to be a jockey by the time I was 5'11", so that worked itself out.
