How does one live Orthodoxy...? In my case, poorly!
I think a lot of it boils down to cultivating the virtues... love, repentance, humility, etc. I tend to read and talk, but that's probably not a very good way of going about it, especially for someone inexperienced in the more crucial things. So... prayer is the place to start I guess, with the guidance of a priest or spiritual father if possible. Trying to do something every day to take a step forward, in cooperation with God. It can often be something that seems fairly mundane. Something "normal," like helping you aunt or grandmother get to the doctor, that might help you make more progress than read a dozen books. Which is not to say that spiritual reading is not profitable, only that it's only when we stop focusing on theory and actually start living things out that we make progress. It's sort of like putting together that complicated doo-dad you buy for Christmas: it's all well and good to read the instructions and try to get some understanding of the overall scheme of things, but until you start actually working on it, all the info in the world won't be of any worth.
So... read Scripture, then put it into action. Read the Church Fathers, what they say about love, or repentance, and how to make those real in your life... then do it. Read that contemporary spiritual work, by all means--but when you've read the last page, you may have finished the book, but (hopefully) you've only begun to actually profit from the text, because the profit comes when you can actually use the information. Sometimes using that information will be overt action--giving your time, going to confession, speaking more gently and peacefully to someone. Or it could be something more internal, perhaps understanding your sinfulness or fallenness more, or perhaps on the other hand getting a real sense of how special you are as being made in the image of God and capable of striving for likeness with God.
One good thing about reading and discussing is that you come across methods and activities which help you in the spiritual life. Prayer, yes, and fasting, and the sacraments of course. But then there are other things, such as praying the Jesus Prayer when you find yourself having issues (e.g. annoyance or anger), adding prostrations or bows to your prayer rule, admiring God's creation, or reminding yourself how lucky you are to have X, Y, and Z. Then there are many ascetic practices beyond that (sleeping on the floor, restrictions on food, etc.), but for most of us we're probably doing good just trying to get the basic stuff covered--saying our prayer rule, fasting when appointed, reading a bit of the Bible each day, trying to learn what the Church/Fathers teaches about this or that, and generally just being a decent human being. And we may slip up every day, but that's ok, as long as we are trying. And maybe we'll only take one step forward that day, and that's fine. Theosis will go on for eternity.
