Gene Roddenberry, the creator of the Star Trek empire, envisioned the iPad long before it actually showed up. He saw that there was no need for commerce with a money exchange because people were recognized for their capabilities.
As a tool, money has two metrics: either it's positive or it's negative. Your goal is to generate more positives than negatives.
To be a successful entrepreneur, you have to let go of the need to have money. Your business needs to be a confluence of your purposeful passion, a viable marketplace need and sustainability over time. When you are in that state of conscious awareness, obstacles will melt, challenges will feel like invitations and money doesn't even register on your radar screen because it's not important enough. Money is a by-product of providing value.
You cannot justify a business solely from a money standpoint. If you try, or actually make decisions from that perspective, you're making decisions from your ego.
Altogether, your perception of money will determine how successful you feel but not necessarily how successful you are because it's all relative.
