Are liking it and being good at it the same thing?

I'm still working on my fluid dynamics take-home exam, and I think I've got about 10 to 15 points partial credit (out of 100 for the exam) so far.

I'm hating it. I'm hating both fluids and scientific computing. Which is making me wonder if I'm in the right field

I've always thought that liking something and being good at it went hand in hand. Maybe I'm wrong. I've always had extremely high math aptitude, well into 99th percentile on all the standardized test scores and A's in any math course I ever put the slightest effort into (and even some that I didn't). But do I really like it?

If I'm honest, I have to say no, not especially. I like it more than most people, probably because I'm good at it, but there are a million things I'd rather be doing most days. I don't do anything particularly mathematical as recreation. I don't think of math on my own time like real mathematicians do.

So maybe liking something and being good at it aren't so closely related as I thought? What I'm beginning to suspect, and probably should have known all along, is that aptitude can carry you surprisingly far with little effort, which of course you won't put forth unless you enjoy something. But at some point, that's all she wrote.
