I recommend paleontology (the study of dinosaurs).
The reason I recommend paleontology is because it’s so fun. There are so many things to do, like digging up dinosaurs; I mean seriously, how many times have you been told not to dig in the yard, and you’re digging up dinosaurs, dinosaurs! Well, they’re bones, but they still look amazing, and if you find almost a full skeleton, you could make a fortune! And the reason I say almost a full skeleton is because no one has ever found a full skeleton, but if you did you’d be rich and famous.
Maybe you’ll find a new dinosaur, then you’d be richer, even more famous, and you’d get to name it.
So that’s why I recommend paleontology.
