Math.
Nearly every math textbook comes equipped with the answer to nearly every math problem at the back of the book. I always checked my answers when doing homework to make sure it was correct. When I wasn't finding the correct solution I would work backwards with the answers provided in the back of the book and figure out how to get to it. There was seldom ever a math related homework problem that I couldn't eventually figure out how to get the solution for. It wasn't until I got older and the math problems became more difficult that having the answers at the back of the book no longer helped me figure out the solution. And then, even when I had the solution handed to me, I wouldn't be able to remember how to replicate it again in the future. It's hard to comprehend now how I ever used to feel such an immense sense of satisfaction and happiness when it came to anything math related. Math just scares me now. It taunts me and makes me feel incompetant, along with so many other aspects of life that I've encountered during my introduction to adulthood. Real life doesn't come with any answers at the back of a textbook. There's no way of working backwards or of checking to see if what you've been doing is right. Some problems won't even have a solution. However, some things that math and life have in common is that ignoring it won't make it go away or get any easier. Seeing so many unknown variables together in one place can be--to put it lightly--overwhelming. But somehow, remarkably, if you allow yourself to appreciate the challenge of it, it has the capacity to be strangely... elegant.
