While in university, one of my necessary classes was a geology lab where we had to study rocks for one class a week--two hours and fifteen minutes. I was never more bored and burnt out.
I'm glad though that you enjoy it!
I loved geology classes in college and considered becoming a geologist but was intimidated by the mathematics required by the chemistry aspects of geology. Decades later, I realized that I can do math as well as anyone else but always mistakenly thought that I was stupid because I literally memorized how to perform mathematical calculations. I am still fascinated by geology and have quite a collection of rocks from around the world.
