Math and science. I see them as relatively easy. Alot of people seem to consider both of them as being relatively hard.
I guess physical intelligence? Alot of people can dance decently well or just excell at quite a few things easily. Some physical things I do decently and others I gotta practice like hell to be competent.
Easy: Writing essays (SO easy), writing stories, and math (depending on how much time I give myself to actually learn the subject)
Hard: Social interaction. Like, I'm legitimately socially awkward. I've been thinking recently that I may have a mild social disorder because it can get so bad.
Drawing hands, or faces. And maybe like... driving a stick for people who don't. Or like... doing weird things with my voice? XD People are always fascinated by how I can so easily change my voice?
Animating. It's actually not hard, just time-consuming, but most other people wouldn't know since they might spend more time doing productive things. Took me 3 days (about 4 hours per day) to make a half-decent picture of the Green Arrow.
As for the other thing, I'd say having a life... or sleeping. I don't really do either.
