Synonyms for the word "self-congratulating" include self-praise, self-approbation, self-applauding, self-satisfaction, self-aggrandizement, self-admiration, self-pride, and self-glorification. All these words describe the act of praising oneself excessively and without justification or recognition of others' contributions. Such behavior is often viewed negatively and can result in alienation from others who feel slighted or overlooked. It is important to recognize and appreciate one's accomplishments, but excessive self-congratulation can create a toxic environment and hinder personal and professional growth. Therefore, it is essential to strike a balance between self-praise and humility to maintain positive relationships and foster a healthy sense of self-esteem.
