I think we all have a personal role to play when it comes to making the world a better place, the problem is many of us are gripped by the group mentality, thinking authentically and individually is frowned upon in the current modern society. 

Through thinking each one for themselves, means we can at least realize our unique potentials and via a combination of each and every one of us, come up with solutions to improve, but unfortunately individuality is scary to many, rather conformism is more appealing.
