Ariadne is the guide of the labyrinth. She was originally a Goddess, but was reduced to a Princess. She led novitiates through the mazes. To "follow Her thread" is to travel forward into the unknown to the center of your soul. You are able to find your way back, but are forever changed by the experience.
Invoke her when you get into a car, or whatever. She'll take you to the best places, but you won't get lost, or into any more trouble than necessary for a whopping good adventure. I always take her hiking.
For me, one of the greatest joys of being a Pagan is the endless variety of Deites. There are always new ones to explore, and familiar ones change and evolve. Watching children achieve that epiphany makes everything in life worth while, and you get to share that experience. Lucky you!
