NBSV 075: Jon Goodman on many ways "hustling" is B.S., and focusing on one thing to achieve success

I got to interview my business role model! Jonathan Goodman of the Personal Trainer Development Center, the world's largest site for fitness professionals, is here to discuss why the concept of "hustling" is B.S. (in certain contexts), the glorification of "busy", and how to achieve success by focusing on one area of expertise, surrounding it with good-enough-to-be-dangerous skills in a few other specific realms. Also, career advice for people who have extremely wide-ranging interests. Oh, and seitan!
