When businesses and individuals try to create worth they often forget that it's the perceived value that other people see in what they're "selling" that gives it any meaning whatsoever. Who needs a college education? A new car? Some fancier clothes? Or...the latest knowledge about technology? Well...you do, if you think it brings you value.
Here's the rub - if you give value, people will recognize that whatever they're spending - whether that's time or money - is well worth it. And - if you go "above and beyond" the initially stated product or service and provide even more value than the "customer" thought they were going to get...you're on the road to building great relationships and a solid business.
It's value that the business and individual should look at first, not revenue. Because...if the value is what you say it is (or beyond what you say it is), then - most assuredly, the revenue will come.
Look first at what value you provide and then build your business and/or individual relationships from there.
