I agree the idea of the solopreneur has been appearing much more frequently. Where it really popped up for me was Noah Kagan’s Porcast. He has run a series of interviews over the past few months with solopreneurs making over a million a year. It is amazing just how many do not work quite as much as your would think and make quite a lot of money from just the products you mentioned. It is from what some are saying going to be how people live and work in the future. Each person will be their own business.
