The cartoon character BatFink could protect himself by deflecting bullets with his 'wing shield.' Psychological resilience is a little like having a protective invisible shield that will allow factual and reasonable information through but will reject those things that are untrue and harmful. Unconditional Self Acceptance helps students understand that whilst they will experience failure and rejection, they themselves can never be failures or rejects. Their positive traits, characteristics and capabilities can't be cancelled out or taken away. They remain worthwhile because as Albert Ellis says 'they exist.' This is helpful to all those students who will argue that they are hopeless and without worth.
