I feel this with dog training so much. We got our first dog back in October, then our second in November, and we started obedience classes. I hated doing random obedience without understanding what the purpose for my dog was? Our instructor would tell us, "make him sit" and I'm like "why though?" And to be fair, our instructor tried. They'd say it was for him to focus on us, and I was just like, "but he is focusing on us when he's standing? What is the point in forcing a sit besides control??" And they never really had an answer.
I started taking classes to become a certified associate dog trainer because I couldn't find the answers I wanted.
