It is necessary only for the good man to do nothing for evil to triumph.
Edmund Burke (1729 - 97) British philosopher and politician
The law of reciprocity simply states that "what goes round - comes round", or, to put it another more positive way "you get out what you put in".
It's one of those laws of nature that is not easy to accept, particularly when we have just been the victim of one of the perpetrators of mayhem and mischief that seem to be everywhere.
In simple terms, what people invest in their activities will be reflected in the results. What you put in reflects what you can expect to get out. It's often not easy to accept that the bad guys do get what is coming to them. Often it's not right away, but it does happen eventually.
The reason is, simply, that leopards do not change their spots.
There are those who think they can place themselves as not only first priority, but the only priority. They will use others for their own purposes, and simply not care at the damage and destruction they leave in their path. Because they are so consistent in this behaviour, ultimately it will rebound on them, and hurt them more than they have hurt others.
Naturally it is frustrating to see such charlatans appearing to profit from destructive behaviour time after time.
But experience shows that ultimately, eventually, they always get what they deserve. But sometimes it does take a long time. A very long time. But what goes round does come round.
So, what is the SIMPLE reminder in this? Avoid the need to invoke the law of reciprocity in the first place. Ensure that you avoid the kind of individuals who cause havoc.
How? I find the best way is to work on developing an instinct for people you can trust, and then trusting that instinct. People constantly give off signs as to the type of person they are. By working on an awareness of those signs, by developing an instinct - and then trusting it - it becomes easier to avoid the kinds of situations which do us damage later on.
Most of us have basic instinct which can discern the difference between good and bad, but often we ignore the instinct. The deal was too good. We needed the sale. He had the skill set we needed to develop that division. So expediency, or greed, caused us to ignore our instincts - and inevitably we faced the consequences.
Listen to your instincts and you will avoid the necessity to invoke the law of reciprocity.
