Because the direct route is not easy, or even possible for most people. We are human being living in a commercial society. Money is essential for us to survive. And for most people, a modest level of success is essential for happiness. I think the right approach is to strike for goals which have dual rewards: material and spiritual. Do things you love. If money doesn't come, also do things bringing in money.
