How many times have you not done something purely due to the fact you were scared? It is a challenge to overcome fear, but the fact is it is a block to doing so many different things from tasks you need to do to things that will make your life better. Not only is fear irrational but it is a thing that manifests time and time again until you get rid of the source. Are there any specific methods in overcoming it? Well yes I’m not sure exactly, but awareness of your the fear can help, evaluating it by asking yourself questions and figuring out the source of the fear too. Also there is the advice of taking directing action and facing your fears or small steps such as drawing a picture of your fear etc. Just see that fear is an irrational response and counteract any fearful thoughts.
In fact it is fear that ensures that you won’t be true to yourself. Society itself is full of it, from groups which scare people into joining, types conformity encouraged as people are to scared to be true to themselves and the fear of change for the better (fear of unknown).
