I certainly second the idea of doing a business around your interests.
You are doing what you like and earning income to support oneself.
What could be better than that?
For few years now, I have seen many who work with no aims.
They simply work for their paychecks and are simply unhappy with their lives... I see no point in "torturing" oneself this way...
I am currently a student also, I am always short of business ideas...
After reading through your posts, I think I would start brainstorming for ideas and putting them down no matter what... Perhaps some potential business can come true...
