My definition of humility is being neither too high nor too low in your estimation of yourself. In fact, the need to compare yourself to others is irrelevant when you’re truly humble. Humility requires self-honesty and sincerity.
Feeling like you’re better than others (and needing to put others down) is arrogance, which is the opposite of humility. Likewise, playing the martyr or victim is also a kind of arrogance, and not humble. It’s only through vigorous self-honesty that the true heart of humility can shine forth.
Being truly humble means being invisible, like the way nature is great without caring if anyone notices. It means living life for the greater good, which includes yourself and everyone else. It means withdrawing blame and taking on full responsibility for your choices.
