Self-assertion is a kind of self-interest which makes the mind mediocre

Self-assertion is a vice.

Self-assertion is a kind of self-interest, where everything turns around the Ego, and therefore makes the mind mediocre.

To live in a world, which is controlled by self-assertion, without being self-assertive, means, truly, to love something for its own sake, without seeking a reward, a result; but this is very difficult, because the whole world, all your friends, your relatives, struggle to achieve something, to accomplish something, to become something.
