To earn Substantial Bread you must serve others, to earn Supersubstantial Bread you must serve the Daimon. Both are necessary, but you need Substantial nourishment first. This builds the basis from which you can aspire to Supersubstantial nourishment.
It is a great irony, that in a free market the best way to help yourself it to create something that is valuable to others; so valuable that they are willing to exchange value with you for your creation. It is very simple and it is something that everyone does everyday, maybe even hundreds of times. Someone created something so valuable you are willing to voluntarily exchange your own representative value i.e. capital, for it. Their hamburger is worth more than your $5 so you exchange, their pair of shoes is worth more than your $40 so you exchange, your labor on this or that is worth more that $15/hour to an employer, so you exchange; and the list goes on and on. Millions of exchanges of value every day that makes everyones life a little better, a little more substantial.
This is the free market; this is Capitalism; and the reason I say it is an irony is because popular opinion holds that Capitalism is the greatest epitome of selfishness. Yet just the opposite is true, for mankind is best served in pursuit of individual rational self-interest.
Go forth and seek nourishment so that you might become Supersubstantial.
