Difference between British and American is mostly spelling (colour vs color, grey vs gray), but also expressions and sayings, occasionally complete words (trousers vs jeans, or telly vs television). The spelling was the easy part, but having to know the different words was where things got complicated. I still mess that up occasionally, though it helped when I started to see them as separate languages.<br/><br/>Rowling wrote her books in British, but for the American market they were 'translated' into American, using the local American words instead of the typically British words that she used. I read that it caused some accidents with the fantasy words that she used, where the American books ended up having a couple of mistakes. I don't think it impacted the success a lot if the books weren't localised, but it probably did contribute a little bit. I don't have the time or energy to write localisations for both markets though and since the number of American speakers outnumber the British with roughly 10 to 1 I decided to go with American instead. Additionally that's also easier for me to write in since we hear almost only American in movies and on television here. British is unfortunately pretty rare, even though I love the accent.<br/><br/>With my autism I actually have more advantages than disadvantages. I've worked very hard ever since I found out about it to fix the disadvantages (which are mostly social related) and I'm really benefitting from the advantages it gives me. Once something gets my interest I don't stop researching the subject until I become nearly an expert at it. I can be quite obessive when it comes to that, -snicker-.<br/><br/>It does generally take me longer to learn something than other people, but at the same time I'm much more thorough as well. To take an example, it took me 4x to pass for my driving license and I ended up paying twice as much as the average person, but because I like routine and I'm good at following up rules you generally won't catch me quickly at making mistakes while driving, which turned me into a pretty safe, though perhaps somewhat boring, driver. (I always valued safety over speed anyway.) :-)<br/><br/>It's quite shocking to see how some maniacs are driving around on the road and it made me wonder how they ever passed the exam.<br/><br/>The only really big disadvantage that I have is getting and maintaining a relationship, but I'm even working hard on that one and making steady progress there. It's been trying times though, I know of many autistic people in the same situation that are staying single because they can't find a good partner. I'm just glad that I can learn from the mistakes I make. I worked hard on getting in an attitude of finding a challenge in the problems I encounter and work to overcome them, rather than giving up and just let things be. To me life will never be easy, but at the same time it's also more rewarding when I do succeed at things. ^_^
