When I write to myself (normally about technical matters,) it helps me to understand and appreciate how differently my mind works, and how difficult it must be for someone "normal" to understand what I am trying to explain to them.......because I find it hard to use concise phrases and unobscured terms to express myself - even to myself?!
Personally, I do better at explaining myself verbally....but I certainly know that this is not common amongst autists?
How do you, most successfully, communicate complex things to other people.....and how can you know the answer to that question?
