Something you're just good at with minimal effort and/or you learned much more quickly than average.
For me, it's paper snowflakes. My brain just seems to effortlessly figure out what cuts to make to the paper wedge to make it turn out exactly how I want it. Largely useless, but good fun and was a much-needed ego boost when I was a kid :]
I have a strong visual sense. I can create movies in my head, and skits. Helps with art and writing.
Also, I'm emotionally intelligent. Unfortunately I'm also incredibly sensitive/and a cry baby. :/
I came here thinking I had no natural talent, but this resonates with me.
I always wanted a device that I could wear that would play what I'm hearing/seeing as I'll make up entire songs in my head. I can "hear" everything, but I can't play a single instrument lol sometimes I'll hear just a few notes and then it's off to the races as a whole new song is going on in my head based on just those few notes.
On the direct opposite... I'm an aphant, meaning I cannot visualize in my head. I do "visualize" or imagine places, but there is no actual visual aspect to it.
I've seen it described as a desktop PC with no monitor attached. All the information is there, it just does not get rendered.
Some people see it as a hinderance, but for me, it's just the way I think.
