Chapter I (introduction).
	Have you ever thought how wonderful paper planes are? A flying, aerodynamically well-designed airplane, made by folding a piece of paper a few times.
	Thump! One of those just flew into a wall. Joe sighed. The plane was supposed to do a flip, but it went in the opposite direction instead. “Whatever I try, it never works out”, Joe thought. “I couldn’t even study well enough to stay in college!”
	His fist furiously hit the desk. “I could’ve become a famous psychologist by now!” His illness was quite a big obstacle on his way to a psychologist career. Joe suffered from memory blackouts.
	He took a deep breath. “Work’s not going to do itself, and I’ve got bills to pay. Depression can wait”, he said. Just as his pen clicked, door has opened. Joe’s heart stopped for a moment – if his boss came here, Joe’s doomed. Fortunately, it was Ben, calling Joe for a coffee break. He sighed with relief.
