The practice of too frequently using the word I; hence, a speaking or writing overmuch of one's self; self-exaltation; self-praise; the act or practice of magnifying one's self or parading one's own doings. The word is also used in the sense of egoism.
It has always seemed strange to me... the things we admire in men, kindness and generosity, openness, honesty, understanding and feeling, are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest, are the traits of success. And while men admire the quality of the first they love the produce of the second. John Steinbeck
The worst disease which can afflict executives in their work is not, as popularly supposed, alcoholism; it's egotism. Robert Frost
If a person loves only one other person and is indifferent to all others, his love is not love but a symbiotic attachment, or an enlarged egotism. Erich Fromm
