[HELP!!] a short preface

Dear italki users,
I have written a short preface of an essay which tells a story of a journy in Europe.
I'll really appreiciation it if you correct any grammar or word choice mistakes in the text.
(I marked also some parts that I specially want to get some advices)
Thank you in advance!



Dear readers,

This is [name], the writer of this essay about a journey to Europe << when I talk about the moment >>
First of all, narration is included with this book. You can feel the sentimentality of European through your ear by using the QR codes included with each episode.
Some of you might wonder if you are on the right track of your life.
After reading this book, I hope that you can relax a little bit, and take some time to look back at yourself.
(!!here 'look back at yourself' can sound judgmental? I want it to sound neutral.) In this case, "Look at yourself" doesn't sound judgmental! Don't worry!
I wrote the moments that were telling me that the decisions that I had made in my life were not so bad.
(!!would it be better to say like this?: Here in this book you can find the moments that helped me realize that the decisions that I had made in my life were not so bad. This is better, but I've made some corrections)
I want to share my method of relaxing with you too.
I’m looking forward to seeing a world where steps taken by children are encouraged,  so that we can have true freedom in our hearts.
