Nathaniel Branden said this quote
“ Genuine self esteem – please understand this – genuine self esteem is not competitive or comparative. Genuine self esteem isn’t expressed by self-glorification at the expense of others, or by trying to make yourself superior to everyone else, or diminishing others in order to elevate yourself. Arrogance, boastfulness, the overestimation of your abilities, reflect low self esteem, even though we’re often encouraged to believe the opposite. In human beings, joy in the simple fact of existence is a core meaning of healthy self esteem. Thus understood, how can you possibly have too much of it? ”
