Do I think a lot?

Good Morning everbody, First of all let me introduce myself. I am a university student studying at the University of Greenwich, UK. I am currently pursuing a degree in BEng(H) Electrical and Electronics Engineering Technology. I am 19 and love business! OK, I know that was a bit of ambiguity there in that sentence, but its true. I want to be build a successful business because this is what my instincts tell me to do.

But the only problem here is..... that my mind keeps changing its own direction. It never stays in one single lane but wants to drive on every highway and that too at the same time. I seriously need to control my thoughts and learn to stick to a single decision before changing on to the other. My aim is to become a successful entrepreneur in life and that too before I graduate. I know that seems pretty foolish but this is what I really want to do and once I do this I would regard this as the first step in life! So, I would recommend everybody to keep checking back and do post in your comments and try to enlighten me with some advice.
