[this is fun]

Thank you for the replies.
I see many have kept journals at some point. I'm thinking about trying that, I've never done it. Maybe I could make 30-day trial with it.

@Daffy Duck, you say you've kept journals. Did you write about something until you reached a solution/had an 'aha' moment and then just let it go? Or did you re-read it after some time and then everything fell into place?

@brendannz, the same question as the one for Daffy Duck. As far as setting goals, weekly and monthly plans goes, yes, I write them down too.

@lasti, it's basically what jaamkie said about the difference between speaking and writing. You say don't speak much, is it because you don't feel the need to go into details about something or you feel nervous talking in front of more people? Because a friend of mine, who also doesn't speak much, says that he just doesn't feel the need to explain things all the time.

@jaamkie, yes, this is what I was getting at, the thing where you speak about email debates, you have to refine and sort of 'build' your arguments.

@Eric Roosevelt, I used mind-mapping only when I had to study for some exams. It was very useful. If I understood you correctly you used it for other types of 'problems'? How did that go, you would write down all your possible solutions or?
