The Amazon reviews weren't too kind to him.

Looks like someone who tried hard to get into this industry, even breaking some rules along the way, but quit once he got to the little leagues.

This is a 30+ year career, and you have to earn your stripes, literally!

For perspective: Doctors come out of 8 years of College/MedicalSchool to spend 5 years in Internship/Residence making $45-60/year working 80 hour weeks before anyone will take them seriously and they earn the next step in pay. (their student loans are much worse than yours!)
