I have come to believe that it is essential to re-evaluate your beliefs from time to time. We are all taught things when we are young, usually with the best intentions, but as time and science and maturity come to pass, those beliefs (that we may have held as truths for years) do not always hold water as we learn more about the world for ourselves. It can certainly be difficult to admit to ourselves, that we have been wrong about something for 20 or 30 years. But isn't it more difficult to hold onto a belief, that in our hearts just doesn't sit right anymore?
