precariously

If something is happening or positioned precariously, it's in danger. A glass could be precariously balanced on the edge of a table. You're living precariously if you jump up and down on a lake that's not totally frozen. In your late teens, you're precariously close to the brink of adulthood. When you have one college class left, you're precariously close to having to find a job. Some people like living precariously: they enjoy danger. Other people just get stressed out and prefer to live carefully.
