Some organizations, though, work to find competition instead of fleeing from it. If you have a system, a point of view and a process for growth, then a market that already exists is your friend, the next place you can grow. And so, for example, small chains like Five Brothers and Shake Shack are happy to set up shop right next to fast food places that might represent competition.
This is one reason Amazon's efficiencies are so fearsome--they prefer to start in a market with competition.
On the other hand, if you're depending on being alone in your field, then your charitable cause, your brokerage business or your industrial entity is going to have a hard time finding the next place to grow.
(Semi-related trivia: In high school and college, I was so bad at school elections—losing every single one—I finally decided I would only run for slots where I was unopposed. Amazingly, I lost that one too, and wisely stopped competing for votes—sometimes, competition is a choice.)
