The slash effect

Just discovered a book by Marci Alboher called One Person/Multiple Careers - the slash effect. New model for work/life success." anyone else read it & what do you think?
Hasnt Barbara been saying all this for years?
The only thing that hesitates an A+ from me is can we really take a guy seriously whose a dentist, selling nutritional dog food in his waiting room and doing stand up comedy jokes (yes hes a professional comedian) as he checks your teeth?? (really happened to me - but for some reason I didnt stick with him..) I guess thats being unfair.
I think Im for the 'umbrella' system. Things sort of relating??
Opinions please.
