Not recommended.
This is very empty and vague.
It's basically a PDF, with ugly and unreadable font + bad page spacing, just printed. It does look very amateur and, yeah, PDF-ish.
Most of the text is non-informative motivational emptiness that does not provide any value, like, for example, the section 'you should collaborate with people' is supported by few examples of what you can do e.g. contact your friends, find the right people for your song etc. This list-like feature of basic things we all know to exist is found everywhere in the book. So, after you'd read this small section on collaboration, the author would move to another list of examples that support a different concept, such as 'Identify your style', which would be supported by a list of things like 'identify your genre; observe music that is out there; identify your strengths'. You get the idea.
No depth.
Apart from these empty lists, the rest of the book is extreme basics of songwriting illustrated – like, for example, the structure of a song.
On top of that, it's a very facepalm-y book. The author uses clichéd phrases, trite and hackneyed humour and insists on writing &!#@ instead of the word fuck as if we were in the year of 2004 and this was catchy and interesting. Instead, it comes off as very cringy.
I truly believe Mr Bell is passionate about his expertise and is well-meaning, however, I do not think this book contains any value to readers.
