The title is addressed for those going through cancer experience, but its something anyone who is going through challenging times can learn from (and who doesnt face challenges every now and then?)
It reminders you to look for the bright side however small it is, if the author in this situation can do it, we should all be capable to it too. And for those thinking, but how? - You follow the 3 simple rules.
The best part is that it takes 15mins to read (if read slowly) so you dont have to feel like you have a whole book to read when you need a reminder. Its some thing we all know deep in our hearts, but need a reminder every now and then when we face tough times. Strongly recommend!
