How do you get more NMT in Animal Crossing?

Hello there! I'm curious about something related to Animal Crossing. I've been hearing a lot about NMT, and I'm wondering, how do you actually go about getting more of it in the game? Is there a specific method or task that rewards you with NMT? Or is it just a random drop from certain activities? I'd love to know your thoughts on the best way to accumulate NMT in Animal Crossing!
