Yes, I find journaling extremely helpful. Sometimes it is just a way for me to get things "off my chest". But other times, I get tremendous insights just by letting myself write freely. Sometimes I'll even argue with myself. I might write something like, "I don't know what to do about that" but then quickly follow it with something like "Ahh, but is that true? Am I sure I don't know?" and then I might end up revealing the answer to myself. The key is to give yourself total freedom to write whatever comes into your head, but then be willing to challenge yourself.

I don't usually have too much trouble talking. Sometimes I can't think of the right word in the middle of a sentence, but it's not usually a major problem. My brother, who has dyslexia, seems to have more trouble with that. Whenever he speaks, there are always significant pauses while he struggles to find the words. And then sometimes he gets frustrated if he is misunderstood.
