The passion economy is a collective of people swapping what they love to do for money.
Like any gold rush, the seller of the shovel makes more than the person digging.
My advice. “How to follow your passion and scale” is not talking to your passion but to your instinct to make something of yourself.
Instincts are helpful when you fall but less helpful when they are telling you to make something of yourself.
Buyer beware. Use both your heart and your head.
