If you are doing a business, look for one with a comparative
advantage. If I am selling clothes and you are doing likewise, what
makes us stand out? There are thousands of others also selling
clothes, are you fighting to survive or to grow your business? Are
you the next bubble tea or the next coca cola? 
Think of it if someone has 1 million dollars of capital to
compete with your business, would he be able to bring you down? If
the answer is yes, your business suck. If no, you have some
competitive advantage.
Competitive advantage can be many types: Monopoly, oligopoly,
lower cost, wider distribution, branding, superior product,
location, patents, specialise skills and many more....
