The first book was awesome, the laracon talk also was, and I'm starting to think everything Justin does is worthy just because he made it.
I found the course more useful than the book, though it might be an idea to get the book first to see if it's relevant to your needs.
I'm using Justin's approach as I build my side hustle and it has really helped me get clear on what I'm doing.
Also, I met Justin at a conference this year and he is just as cool and genuine in person as he his in the book.
