I have found no greater satisfaction than achieving success through honest dealing and strict adherence to the view that, for you to gain, those you deal with should gain as well. ” Alan Greenspan (born 1926); American economist

Nothing says that your dealings with people need to be a zero-sum equation. You don't need to find a way to take advantage of someone or twist the interaction into your favor. I find myself interacting with people more and more these days in ways that benefit us both. We can work together for the betterment of others.
