This is true. I think that people should have the capability of being successful, but only if they do approach it like a full-time job. That doesn't, however, guarantee success, even a large operation like the last one I worked for can fail.
If it were easy, and everyone could do it and make as much money as working full-time, without actually working full-time; then everyone would.
