The cup is half empty. The cup is half full. The pessimistic and optimistic tone gives it a different connotation.
A i think. sorry if i’m wrong
I think this quote is trying to say you need to be yourself and not follow the crowd. There are so many people who act the same because that’s what’s "expected" in society. If you continue with the flow and don’t go against it, you will end up being like all the rest without even realizing it. Hope that helped
