In this our 21 Century, no one wants to go with someone without a value , for someone to be important in the society and won't be left out in the society you must have a unique thing that you offer that will differenciate you from others or a problem that you help people to solve and this in turn gives you value , it can be skills, Advice, Mentoring etc. The Ecomists said that the value of money is what money can buy. In order words if you relate or imply this to humans, that means the value of a person is what that person can offer.
