The problem is that most don't know how to look. Maybe some of the following can help. First, if you're looking for an easy way, forget it.
Any entrepreneurial venture requires a great deal of hard work, patience, dedication, etc.
Looking for an easy way is just setting yourself up to be taken. There are a lot of vultures out there looking for you. Second, go get a copy of Peter Drucker's Innovation and Entrepreneurship for how to look for opportunities. It's available in paperback from your local bookstore. In it, he maps out where to look, what to look for, and even suggests appropriate strategies for taking advantage of what you find.
