Why i choose this career?

When i was a child, i always want to be in the university. My parents don't push me to choose this, it was only for myself, but i didn't know very exactly what i want to be in the future. I think in so many careers that i can be in.
First, i think in money because, when i was 13 i only think that maybe i would be nice in any career, but the money are more important, so for me it wasn't really matter. When i grew, i was thinking more in how much i love to teach, and that was my central point to choose something. Yes, i wanted to be teacher, but, about what? because, i hate almost whole subjets of the school, and i really was thinking about History but it wasn't really satisfy my needs, so i think in another options, and in that point my mind explode, i always remember with to much love that part of my life when i have a lot of explotions on my mind and questions like; what i will do with my life?, and that is the answer to why i choose this career. I really like the process psychologics of human, the way of mind works, and everything about that, so my mind did click, i want to be teacher of psychology in the university. But now my question is, ABOUT WHAT? and honestly, i really don't know hahah, almost i've seen in the career make me feel great with my decision, but i have a lot of time to focus myself about of what way i'm gonna take. I didn't expect in this moment something secure, i'm always open to change, but that's the way of life goes on, so i'm gonna be.
