Sagittarius is one of the most intellectual signs, due to their insatiable curiosity about the world. Your mind needs constant feeding, or you quickly get bored and restless.
So you may find yourself reading books, articles and news sources, or trolling through Facebook and Twitter to meet your need for daily information.
Your brain ends up being your passport to all that's fascinating in the world. You make friends on your travels, but you also make friends based on your shared interests, forming lifelong relationships.
It's also your passport to fun, as you spend time finding brand new ways to feed your mind!
