Morality and Self Interest
Conventional wisdom has it that moral behavior is thinking of others more than ourselves. We all need to look out for our own self interest. Morality is in our self interest from a mental health and happiness perspective. If we engage in immoral behavior that leads to self hate and low self esteem. That in turn leads to social failure with other people. Engaging in moral behavior leads to self love and feeling good about ourselves which in turn helps us socially and helps us achieve success in life for that reason. If people like you then those who are in the position to do so will help you climb the ladder of success.
