Is this normal?

I am so so so confused about what I want to learn in college. This is my main goal: to learn what everyone else thinks about everything, and then to tell people what I think about something. In a more concrete sense, I want to go to school for an absurdly long time, become a college professor to make money, and then hopefully write something someday that changes something. The first part of the goal (learning what everyone thinks about everything) is unrealistic, thus, the dilema.

My immediate problem is how to pick the major(s) that teach me the largest possible quantity of ideas that exists in the world, including but not limited to, religion, philosophy, politics, art, music, science, history, linguistics, etc, etc, etc.

I think for now I am going to stick with Literature. But I am torn about my second major. And I am torn about whether or not it is pathetic to hide in philosophicalness, and whether I should force myself to deal more with reality.

Advice please?

Also, I am a huge dumbass for not buying my textbooks sooner, because now all the used ones are sold out at the library. Not that I have enough money in my account for them anyway. Gaaaahhhh stress.

But other than that today was good, classes seem fine, I love being back at school, and only 18 more days till Sufjan!!!!!
