ROI measures the amount of return on an investment, relative to the investment’s cost. To calculate ROI, the benefit (or return) of an investment is divided by the cost of the investment. The result is expressed as a percentage or a ratio.
"So, what's in it for me?" Most people want to know if they give you something how it will benefit them. ROI is easy to calculate when you are talking about tangible investments. What about time? What about emotions? What about expectations? When we invest in people, we don't always see immediate results. We don't always reap the benefits of everything we sow into people's lives. It's ok. Life has a funny way of bringing things full circle. Continue to live. Continue to grow. Continue to sow.
