in randomly discussing the issue with my sister, she pointed out that when i try to convey these ideas that suddenly strike me, i am often speaking very fast; and that i was speaking so fast because my tongue was desperately trying to catch up with the train of thought going on in my head, which has moving on too quickly ahead.
the solution i'm now trying to do when i remember, is to speak slower, so that i (hopefully) have more time to formulate what i want to convey verbally. and that perhaps this will also help with the problem of having my mind racing too quickly ahead such that i end up forgetting what i wanted to say in the first place.
i guess having pinpointed this problem may also have helped to partially explain why i write so much better and in a much more organised and logical fashion than i speak - i buy myself the time to sort through the various ideas, trains of thought, and to organise them into much easier digestible bits.
my sister is a genius. it was truly a revelation to me when she identified the likely root of the problem - that i was playing verbal catch up with my mind.
while written out like this, it may seem like total common sense to anyone. but i think it requires (i) good observation skills to first become conscious that such a phenomenon is even occurring, (ii) some insight to come to the realisation that it is likely due to a mind-tongue disjunct, and that she is (iii) articulate enough to bring verbal form to that mere consciousness / realisation that could just have occurred at the back of anyone else's mind.
i don't wanna go all economics-sounding or what, but that almost throw-away comment is such value-add to me! gimme more!
