G_String,
Not everyone feels their first solo was a fantastic experience. In my case I was so anxious to get my licence and go off flying on my own that I was just glad it was over so that we could get on to doing some cross countries, and I was a bit embarrassed by all the fuss. Your own personality comes into this quite a lot. You realise you didn't do everything as well as maybe you could, which is fine. But don't be too hard on yourself - remember, the good landing is the one you walk away from.
