I have read how to win friends and influence people. Humility may be "likable." It is really unproductive in that 1. It 's genuine and therefore a person is poorly qualifying their value possibly. 2. It 's disingenuous.
Humility is a negative emotion.
Giving credit where credit is due is productive as well as telling those you value why.

Society teaches us to not be proud, it's unbecoming and might makes others feeeeel bad. (And it's one of the seven deadly sins.) Without pride in yourself you will not achieve your highest potential. You have to read a lot of Rand to understand the full meaning of this quote. It's all about reaching your highest potential. Loving life. Not letting others destroy you via various means.

This is a bit of nonsense and one of the places where I break ranks with her philosophy. How obvious and unfortunately often it is that people overestimate their own importance and think too highly of themselves, thereby cutting off growth to their true potential. A necessary ingredient to learning anything is to have the humility to recognize you have learning to do in the first place. Even the one that is the "best" at something is better off holding an attitude of wondering how much better they could be if they kept working at improvement, than to have pride in what has been accomplished and have it end there. Having an attitude of humility towards ones accomplishments does not equate to being unhappy, and having pride in ones accomplishments is done a lot these days, when the accomplishments are not at all any big deal when measured by the standards of past generations. Sometimes Ayn Rand spins up a strawman of a definition about something and then proceeds to set it on fire. Just browse over to dictionary.com and check out the definition for humility. You won't see anything about humility being the state where one does not value themself, or the state where one is not happy. It is all about having a modest (moderated) opinion about one's self-worth, versus (see definition of pride), "an inordinately high opinion". On the spectrum between pride and the opposite of pride, humility strikes me as being balanced in the middle.
