I've been focusing on self studying mathematics for the past couple months, and I'm currently working on discrete mathematics. Here's my attempt at a metaphor to describe my issue.
Imagine you have a jar, whatever is in the jar represents the knowledge you possess. When learning something like the natural sciences (physics, chemistry, etc.) it's like pouring a liquid into the jar. The ideas form more smoothly in your mind, and fit in more naturally with the knowledge you already have.
But when I'm studying math in particular, sometimes it feels like dumping lego bricks into that jar. It can feel jarring and unpleasant. Each theorem, definition and proof is like a singular lego brick. And you see how the pieces might fit together, but the bricks aren't quite connected to eachother yet. In fact, they just form a jumbled mess right now.
If that made sense to you, I just want to know if this is natural. As interesting I find mathematics, the jarring feeling I described earlier can make it really unpleasant to read through a book. And this can be very discouraging. It's like you find something interesting, but at the same time you find it unpleasant. How do you overcome this, is it just a matter of persistence?
