Yes this is possible. We live in an informative world and our thinking can be changed by a brilliant piece of logic in an argument. We can change.
Change is progress and this is something which is needed to fuel the world forward. Too often people are stuck in their ways but more importantly is embracing people when they make changes regardless if they are good or bad.

Consider change as moving forward and embracing the evolving world we live in.
