Parasites are opportunistic organisms that live of contributors to the eco-system. They suck the life out of their host and thrive as a result. Building a parasite business is easy and profitable – in the short term.
Since it adds no value, eventually the host realises what’s happening and removes the leach. Usually, the leach does not survive this encounter.
Symbiotic relationships improve the lives of both parties as the complement and serve each other. This creates powerful allies that will defend you from destruction because you make their lives better.
There are many of both types of businesses. The one is easy first and hard second. The other is hard first and easy second.
The choice is yours.
