Hello, Need means to require something because it is very essential while Opportunity in the other hand is a vacancy through which one can supply a demand that is not currently being filled. You don’t go into business because u NEED money, that’s poor reasoning but a good reasoning is ” we are 20miles from a dry cleaner and there are plenty households in need of drycleaning services”, that’s an opportunity. If your business does not solve a problem it will not last. Have a wonderful day ahead.
Have a lovely day ahead.
