Start by reading about Humility, and what it is, and what it isn't. Entire books have been written on it by Saints. Read one.

You wont learn what humility is, completely, by asking on a forum.

If you start examining the intentions of the actions you do throughout the day, you will find plenty of things to mortify before you need to be worried about being pushed around by other people.

In fact, the only person who will notice you trying to be more humble is probably yourself, since it will cause you so much pain.

For example, before striking a conversation with someone or just offering an opinion or compliment, etc - think about what you really intend with that action. Are you truly interested in the conversation? Will your input have any effect? Or are you just talking for the sake of talking? Is it just your automatic reaction to give your opinion? What if no one wants to hear your opinion? What if people just talk to you out of pity and really they find you to be obnoxious and a blabber-mouth?

When you do a certain physical action, or make certain noises, is it really subconscious, or are you doing it to get attention? Telling jokes, etc.

Once you start examining the root of all these actions and start mortifying them, you can be said to have just begun the steps it takes to be truly humble.

As you can see, it has nothing to do with people being pushed around. It's about introspection, and reflecting on who God is, who you are, and that many, if not most people, don't really care about you or your opinions in such a way that you need to strive for their attention.

One danger in this method is that you can then fall into sins of anger and jealousy of other people when you see them talking, making gestures, etc that seem totally superficial and done for self-serving intentions. To allow yourself to think like this is dangerous. Never assume good intention on your part, always attribute the actions of others to good intention or simple ignorance, unless shown otherwise.
