One awesome thing nobody knows about Crabs...You're such a homebody that some may not know that you harbor a secret wanderlust. Proof: some of the most worldly celebs are Cancers: Prince William and the Dalai Lama.
Yes, you love to be in familiar surroundings with family and friends, but deep inside you long to travel the world, see new places, taste exotic (not too spicy!) foods, and try new experiences. If only you could take that comforting, protective shell with you!
Perhaps you can. Focus your trips on an interest, such as searching for that one trinket that will complete your collection or volunteering on an archaeological dig. You'll combine focused travel with meeting like-minded souls and seeing new places!
