There are people who their whole life seek to take from others. They cheat, lie and steal their way through life. They are not necessarily criminals blatantly robbing a bank. They could exist in an office, the corner store, a social group we belong to, or in our families.
They all have one thing in common. They believe that the world operates on grabbing scarce resources for themselves in any way that they can whether it is power, money, or resources.
They believe that they only do what everyone else is doing; looking out for number one. Relationships are always to be manipulated and used to benefit themselves. Anyone who doesn't is considered a patsy and fair game. It's a what's in it for me approach to life.
There is some truth that there are scarce resources driven by the ongoing need to accumulate for it's own sake rather than what we actually need. It is spiraling demand that feeds on itself.
They leave no legacy behind them when they leave. They have not created anything of value and so will not be missed. How sad to have lived a life that brought no benefit to anyone but themselves.
It is when we create something of value to others especially relationships with others that we leave a legacy. A legacy of fond and happy memories in the lives of people we have touched and perhaps changed. That legacy lasts forever as it is passed down through the generations.
