How do you know if boredom means “this isn’t for me” or just a normal part of learning?

I’ve noticed a recurring pattern in my learning journey: I get really passionate about a new area in computer science whether it’s frontend, backend, AI, or something else. Sometimes I even dive pretty deep.

But eventually, I hit a wall: I get bored, lose motivation, and start thinking, “Maybe this isn’t for me.” The problem is, I feel this way with almost everything I try, not just one field.

So I’m stuck wondering:

Is this kind of boredom normal when the initial excitement fades?

How do you tell if it means you should quit and try something else, or if it’s just part of the learning curve that you should push through?

Is it normal not to feel passion for a field all the time?

I’d love to hear how others deal with this. How do you know when to keep going versus when to pivot?
