Dollar bills are only made of paper. For that matter so are tens and twenties and hundreds and soon. Yet we trade them for cars and house and other precious items. That paper is worth more because we assign it a certain value. Something in your world is worth far more to you than it appears to be worth to others. That's because it has special meaning that very few people would be able to understand. Don't let anyone cheapen what you cherish. Anyone that does probably isn't worthy of your time.
