I can't really explain it, but it's why I've fallen in love with books. It's that feeling you get when you've learned something new and can't wait to share it with someone you love. Or when you get so excited about a subject that you sometimes read aloud so that you can take everything in. Or when you're having a deep discussion with your professor or another student and you finally feel you've grasped a concept or theory that's been eluding you for weeks. Those sorts of experiences are what makes knowledge-seeking so wonderful. One of the biggest adventures you'll ever go on is on the search for the truth about everything. And since there's so much to learn and become interested in, it's just a never-ending time of discovery and excitement.
