This book is half plot, half life coaching. Tomozaki makes some good progress and you can't help but root for him as you see his attitude start to change for the better. The way he's encouraged to turn his relentless, never-give-up attitude that many gamers take towards their games and refocus it onto real life was well done. The book also has some decent insights like how in games you get EXP by winning tough battles, in real life you "gain EXP" by losing those battles. It was also interesting to see how the author incorporated the effect of "the harder you try, the luckier you get." While Tomozaki fails stupendously throughout the story, his losses not only makes him more resilient to future losses, but also give him access to positive opportunities he wouldn't have had had he not failed.
Overall this is an optimistic and positive story that tries to show that by changing your perspective, you can start to do things that may have once seemed impossible for you.
