If you see furry as something you ARE rather than as something you DO, you're a lifestyler, in my opinion. The difference between furry fans and lifestylers is lifestylers see themselves as their fursona in some sense. There are differing schools of thought on what the term "lifestyler" means, which is why it's always careful to use such terms. My definition aligns pretty closely with the wikifur article.
If you're just looking for ways to incorporate furry into your life, there are a lot of fun ways you can do so. Learn how to make costuming (headband ears and belt tails are relatively easy to start with). Draw yourself as your fursona. A friend in college introduced my roommate and I to furry because he noticed that we drew ourselves as anthro animals on the dry erase board on our dorm room door. Try making sculpy figurines of your fursona, or collect plushies. Wear t-shirts with animals or anthro animals on them, seek out local furmeets, and go to those conventions that you can afford to go to. If you can't make it yourself, get or commission artwork and costuming. Yeah, full suits are expensive, but ears and tails are generally affordable. Try online role-play featuring anthro animals, or try mucks, IRC, or Furcadia. There are lots of things you can do. We have a very rich community.
