Starting a business is like going on a diet. Every "success" story is about finding that one invaluable secret that changes everything. There are self-help guides, blogs, books, and videos each with its own road map to "winning". No startup would fail if funding and customers were as easy to get as generic "advice".
In reality, successful entrepreneurs often benefit from factors over which they have no control. Don't assume that emulating a successful startup founder is the path to entrepreneurial success. Whatever worked for them may not work for you.
