According to personality theorist Rollo May, when a person gets out of their comfort zone they experience anxiety, and when a person doesn’t get out of their comfort zone they experience guilt.
Anxiety results from doing something that you have never done before, and guilt results from not doing something because you’re too afraid to experience anxiety.
Anxiety can be overcome if you’re successful in your venture, but guilt will stick if you don’t move. Thus, it’s better to do something new than to cling to the old.
Anxiety is a matter of success and failure, but guilt is a matter of failure only. Aim for success and get both the anxiety and guilt out of your way.
