According to me, life is an exam; when you are preparing yourself to write an exam saying that "I should answer all the questions and score good marks", "No matter which question comes, I should answer". You prepare for an exam even though you don't know which questions are going to appear. If you can prepare yourself for an exam, then you can prepare yourself for life to face all the situations.
This book is for teenagers to understand what life is. And to accept that no matter who is going to be with you, you have to face all the situations to succeed. Always remember you are braver than you believe, stronger than you seem, smarter than you think and twice as beautiful as you would ever imagine. No matter what you're going through, there's a light at the end of the tunnel.
