Cash flow is the magic behind wealth building

The movement or flow of cash into and out of a business is cash flow. Just as fuel flows through an engine, or glucose flows through a biological organism, cash flows through a business.

To be financially healthy is to have more cash coming in than going out. This could be more fash flowing into your possession as an individual. This could be more cash flowing into the possession of your family as a group. This can be more cash flowing into your organization or business. As long as the cash flowing in is increasing and the cash flowing out is decreasing then you've got a healthy situation from a financial perspective.

Cash flow is the magic because it makes everything else possible. If you're seeking investment and you have good cash flow then people will want to invest in you, or your business.

A business takes cash as input, uses that cash to produce some product and or service to satisfy the demand of a customer, if the customer is satisfied then it's a positive transaction because value has been created, and the rest is profit for the business. So if a business has a lot of cashflow which shows a lot of money coming in, but products are going out, customers are satisfied, and not a lot of cash is coming out, then this is a sign of an efficiently run business operation.
