Connotation of Humility

If it involves painting a "smaller" picture of oneself, it is just another tactic to manipulate people. How can it be any different from exaggerating stuff about yourself? Both involve misrepresenting facts for some perceived advantage in interactions with others.

If it is about not bragging, well, thats good. So is not shouting in public places, not throwing dirt on other people or not doing something unpleasant in general. Do we need to invent words to describe these "qualities" and emphasize their importance too?
