I was very academic - the classic straight A student, got a first at university. Qualified for Mensa though I never actually joined. All my life, learning has just been fun for me. It still is. I'm the kind of person who studies things for fun. Also love cryptic crosswords, logic problems, word games, learning languages - I just enjoy figuring things out, making connections, the process of thinking.
There are definitely gaps! I'm good with anything logical but not so much spatial/ mechanical reasoning. I'm the sort of person who has to turn a map as I follow it. IKEA furniture is a challenge.
I think the best thing about being 'clever' is just the enjoyment I get from using my brain. I'm also very efficient at work, good multi-tasker, learn fast and remember things easily. If I'm interested in something then I can usually do well in it.
Downside: agree with PP that my brain is hard to turn off. I can never just fall asleep, I lie there for ages just thinking about things I read or heard during the day, flitting from topic to topic or memory to memory for ages.
I can also get quite obsessive about something and get lost down rabbit holes, especially online. I love reading but rarely read a book these days: it's all articles and blog posts and Medium / Substack.
I'm fine socially and have a good circle of friends. I find people interesting. I enjoy a good chat about almost anything as long as it's not sport. But I can be impatient, and I get bored quite easily (which is why the endless mine of info online is dangerous). Overall though, being intelligent has made my life much easier and I'm grateful for it.
