You are quite right that a person's emotions plays a vital role in their ability to apply their giftedness. The highest grades (or general attainment in life) are achieved mostly by hard work rather than by being naturally gifted. Being smart is not enough in itself.
Yes, you are quite right. Attainment is achieved by hard work and practice, practice, practice.
However those at either end of the Bell Curve are different.
It's not true that we are all gifted. In fact only a very tiny number are gifted at one end of the Bell curve; and an equal number of non compos mentis are at the other end.
And the tiny number of gifted are different emotionally in that they are over excitable (OE).
And OE and a very high IQ are signs of giftedness.
So there are two things to keep in mind with giftedness and that is the gifted are extremely rare and that they are emotionally different.
My IQ has tested in the 145-150 range. I don't really have a problem with needing to 'dumb down' my speech for anyone, nor do I feel the need to talk down to individuals whom I deem are less intelligent than I. Guess it's a problem particular to you.
I have had that problem as well. I once had my best friend tell me that people didn't like to talk to me because the couldn't understand my vocabulary.
So I got into the habit of adjusting my speach depending on who I was talking to. I don't use big words or obscure words to impress people, but it is refreshing to be around people where I feel I don't have to adjust my words.
Communication is so challanging for me sometimes. My thoughts are too abstract and have to be "translated" into something more concrete. My thought are too intellectual/complex and difficult concepts have to be simplified, over explained or avoided. My vocab is too big and I have to "translate" into simpler words. I could use a word then define it, but it often comes out as partonizing, so I try to avoid it. And people think I am slow because it sometimes takes me a minute or two to form my answer. Okay, once in a while I do try to purposely impress someone with my intellect, but only if they are hinting that I am not very smart.
My official IQ is around 140. With online IQ tests, I have scored anywhere from the 100 to 160 range, depending on the kind I take. I'm generally good with visual patterns and word twisters, but I'm terrible with mathematical story problems.
I consider myself highly impatient, as well. When I want things done, I want them done right now. Unfortunately, that's not the way the world works, and with whatever I want done, I usually forget about it the next minute because my attention shifted elsewhere. But it's this kind of dance that sort of makes up my life. I am also impatient with explaining things to others. And I try to resist doing it whenever possible.
I do not think this has much to do with IQ, though. I do not think IQ tests are good measures of intelligence, and they are certainly not good at measuring anything useful for life. That said, I don't know that IQ has much to do with patience or a lack thereof other than, of course, people who rush through the test to get it over with.
"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
