Confused about Me – Don't wanna do a cooperate job

I am presently 3rd year student. I am good with programming and have done two internships and everything is going pretty smooth. The Problem is that I don't wanna endup working in a MNC. I wanna build stuff. I like to work with startup and I want to build one But I am not getting any good ideas. So, Stuck with it.

Any Suggestion of what I can do know. I even don't like being in College I am thinking of dropping out but I don't know what I am going to do afterwards.

Or anyone with some great idea and need a developer and cofounder I am ready to quit my college.
