Sorry if I'm sounding harsh but I just really wish I was really smart and didn't have ADHD. Maybe then my life could be more exciting.
This is really weird to read. You know I have been diagnosed with ADD myself and I am more than fully aware of some negative sides of it (prone to addiction, difficulty in time management, impossible procrastination, thrill-seeking, not properly finishing projects, and so on) but I am so, so grateful to be this way. My life is exciting just because of my AD(H)D. Actually, I really don't need much external excitement to function, because I see interest in literally anything that crosses my path.
I am a creative person, just because of that. Too many hobbies, and too many interests, but I am never bored, even if I have to stay at home (like during the lockdowns or because of health issues). I also earn money with my hobbies, not much because that's not my goal in life. I've given countless lectures about cultivating a specific flower or workshops about being creative with certain materials. I grow my own food, which saves me money as well. But my joy in gardening is doing experiments with new techniques, companion planting, no dig, soil management, and so on.
I've left the idea of making big money, although I've run a successful business for many years in the past as well. I did it because I enjoyed it.
I don't know your definition of being 'stupid' because I really don't get what you are trying to say. High intelligence means nothing with an empty heart. I know several people with high IQs who can't fit into society because our society is (in my view) not really fit for those people. My own IQ is not that high but enough to understand general scientific information.
There is also social intelligence and I think people who score highly on this scale have it easier in life. They can adapt to situations, understand people's motives and make the most out of situations. Unfortunately, people who are on the high scale of autism, lack these abilities. It doesn't mean their IQ score is on the low side and they can be creative as well*.
And there is creative intelligence, which means being able to think outside of the box. Those are typically painters, sculptors, and designers, but not only them. Anybody can have great creative intelligence even if they don't work in a creative field.
* My nephew recently tried to explain to me his own kind of creativity. He is absolutely not able to create something 3 dimensional or anything out of the blue, but as soon as he encounters a problem (he is a mechanic) he is highly creative in finding the solution even if he has to use things far away out of the box. He has not been diagnosed so far but looking at our family statistics he probably will score both on ADD and ASD.
I think the only stupid thing is calling yourself stupid. That's really stupid. I know people with low IQs who are such wonderful people and I've encountered highly educated people who think highly of themselves but in reality, they are awful people that I don't want to mix with.
Life is simple. When we are born we come here with a backpack filled with skills, possibilities, genetics, and impossibilities. Just look at what you brought with you and make the most out of it. With dignity and respect for yourself. And always realize that we already are perfect Souls. On the outside of a person, you're not able to judge their soul. So-called 'stupid people' are not stupid souls. High technical intelligence can get in your way when your soul's aim was to experience other things in life. Severely autistic people can be highly evolved souls. You never know who is in front of you, never judge the book by its cover.
