He didn't come up with the idea of the "portfolio
life."
But I do believe author and podcaster Jeff Goins deserves credit for popularizing it.
According to Goins, the portfolio life has to do with the sum of all you do and who you are.
In other words...
it recognizes that your life is about more than just your job or the work you do.
It's a collection of all that's important to you.
... And this fits right in with a lifestyle that's oriented toward fulfilling the dominion mandate.
Because exercising dominion involves more than your specific calling or vocation... it includes all your relationships and interests and commitments as well.
And it encompasses your role as a spouse, parent, friend, neighbor, church member, citizen and so on...
It has in mind all the good God intends for you to do... with the breath He gives you every day.
