Because of my autism

I was reading this post here recently. It discusses the fact that many people will explain their children's weaknesses as being caused by their autism, but when the child has a strength that is noticeable, it will rarely be explained as being caused by their autism.
(Joel puts the issue into words a lot better than I have here, so anyone who is reading should follow the link to his post.)
In the spirit of recognising the strengths that come with autism, a list follows of some of my positive traits that I believe are caused by my autism.

1. I was reading before I was three because of my autism.

2. I can be perfectly happy alone, and I almost never feel lonely, because of my autism.

3. I can get along with people of different ages and backgrounds, as I do not notice many of the differences between them, because of my autism.

4. I had learnt enough about music to have composed my first symphony before I was 18, because of my autism.

5. I can focus for up to 6 hours at a time on subjects that interest me, which means that I get huge amounts of work done, because of my autism.

6. I am very much at home in an academic environment, because of my autism.

I'll finish at 7 because it is my favourite number...

7. I can spell almost perfectly, and do sums in my head faster than most people can press the buttons on a calculator, because of my autism.
