If you're looking for business opportunities, look for "dirty" jobs. They are everywhere and in every field. Find them, do them, do them well enough to know why no one wants to do them. And only then get creative about doing these jobs without getting dirty. A "dirty" job is anything that needs to be done but is considered beneath many.
