Sometimes it can be difficult to be open to new information. Critical thinking is a skill that can be a bit of a mind fuck....k, more than a bit. Its a battle between the conscious and subconscious mind - it can be quite the battle depending on the implications of the new information. This is one of the reasons why we are given an emotional guidance system while taking into consideration the intentional fear inducing world we live in. Critical thinking is being diligent, open to all perspectives while you recognize personal bias, current beliefs, etc. Being open to possibility is taking responsibility for yourself and the role you play in humanity. No doubt, some things will shake you if you let it - just remember, you've already overcome 100% of all difficulties you've had. Remember too, you are more powerful than you know genus human.
Another example of how important it is to become aware of your subconscious mind - it runs the show the majority of time by the majority of the population. We are going through times of change - learn to become emotionally intelligent so you can become emotionally resilient. It matters more than you know.....
