Beliefs and Truth are complex subjects.

An un-examined life is not worth living” – Plato So from the point of view philosophy it is everyone duty to examine ones life and Belief for ‘truth’/authenticity

We all have certain core beliefs about life, about ourselves and about the world. These beliefs shape how we see the world and what happens to us. They are pretty much the building blocks on which we create our reality. Now, the vast majority of these are un-examined beliefs, and they were formed in childhood, some often in the first five years of your life. Chances are you adopted them because they were useful at the time, or because you didn’t know any better. Each individual very subtly takes on many of the beliefs of their parents, peers, people they look up to. And so long as these un-examined beliefs remain just that – un-examined – the probability of change is low

As for change. Change happens very slowly and then all at once. Meaning we don’t tend to notice little changes that have to take place before the change we seek appears.
