If "humility" is understood as an opposite (an absence) of "conceit", then "How are 'conceit' and 'identity-view' not the same?" might be a related topic, whose answers are worth reading.
The "stages of path" says that conceit is one of the final fetters (one of the last to be eradicated).
The English word "humility" suggests the presence of a (humble) positive quality. Conversely in Pali many important words instead denote the absence of some quality (see for example anatta, nirvana, etc.). And so I think it is with the word "humility", for which a Pali word is literally "without wind":
Nivāta1 (adj.) [Sk. nivāta, ni+vāta "wind -- down"] with the wind gone down, i. e. without wind, sheltered from the wind, protected, safe, secure
Nivāta2 [identical with nivāta1, sheltered from the wind =low] lowliness, humbleness, obedience, gentleness
For more on the subject I recommend this commentary on verse 8 of the Maha Magala Sutta (Sn 2.4), which suggests associations between humility and:
Reverence: veneration of the Buddha, Dhamma, Sangha; of teachers, wise people, good people ... "in fact, a general high regard for everyone".
As well as being a "view" or practice, respect can be an action, it can demonstrated or acted on,
How does one show respect or reverence? The Buddha says that one gives such a person a good seat, stands up to receive them, makes way for them and, for religious teachers, one places one's hands together and bows at their feet. This is a blessing resulting in good future births and harmony in the present life.
There are other topics on this site about this kind of practice, see e.g. Prostration and attachment to rites and rituals and Tradition and purpose of prostration practice.
Without preconceptions, perhaps suspending prior beliefs, listening (and perhaps dismissing internal monolog when doing so):
The fact that we encounter a number of "blessings" which deal with non-pride should make us realize how important humility is for successful practice of Dhamma. The person who knows it all, who always replies "I know," who has his own theories about Dhamma, or anyone else's theories for that matter, does not have humility. Because of this he can never train under a good teacher.
The metaphors used in second half of that paragraph also remind me of Ahimsa i.e. the principle of being harmless, non-injury, non-violence, compassion:
The Commentary gives the right attitude to have: to be lowly "like a foot-wiping cloth," "like a bull with horns cut off," or "like a snake with fangs extracted." People like this get on with Dhamma. Of course, this does not mean that one is obsequiously "humble" — just another disguise for pride and a revolting one at that.
Contentment: perhaps conceit is a form of thirst -- a thirst for flattery or something like that?
Gratitude literally "knowing what has been done": if you know something it's because you were lucky fortunate enough to have been taught it, so rather than conceit ("I know it") you might feel respect and gratitude ("I'm grateful they taught it")
Timely hearing of Dhamma
One more story -- in one of Ven. Yuttadhammo's videos (I have forgotten which one) he describes his experience of becoming a monk, and if I remember rightly the story was something like (I paraphrase):
When I first started as a novice, I thought "I'm a good monk, a great monk, and I'm better than those other monks." After the first six months or a year I thought, "Well looking back I can see now that I wasn't a good monk. But now I'm a good monk." And, ten years later, "Just a monk."
A lot of this answer is trying to understand or define humility rather than "advice for practising"; and I expect it's missing Mahayana-based perspective. I hope other people will answer this question too.
