Ask HN: Why isn't logic intuitive to some of us?

I struggled at logic and proofs. I struggled at Discrete Mathetmatics and Theory of Computation.

I felt so stupid in those classes, and was demotivated and never put forth any effort. Why isn't this stuff naturally intuitive to some of us? Is the only way to get better at it is to just grind it out and wait till it clicks? Why can't I just see it and get it? Is it because I must learn the language like how one learns the english language?
