According to the Merriam-Webster dictionary , appreciation is a noun that is defined as the expression of admiration, approval, and/or gratitude. It is also defined by thefreedictionary.com as the recognition of the quality, value, significance and/or magnitude of something or someone. 
The date of the first known use of the word was in 1604, and up to this day it is still a big part of society, either between large groups of people or even between two people. Appreciation is important because something so simple can turn an entire situation around, no matter how dire things may be.
There are many different answers for why appreciation is such an important part of your daily life and all sorts of relationships, but one of the most important ones is the fact that it is something so small but it can still affect a person’s entire mood. Nothing can inspire and motivate a person as well as the right amount of appreciation can.
When something that you have worked hard for or slaved over is recognized and is appreciated by someone, people often enjoy a profound sense of accomplishment. And sometimes, that sense of accomplishment at the end of the day is enough to keep you going.
Appreciation can also give you the power to bring up the morale of an entire group, no matter how big. This is why one of the most important methods of boosting morale in the work place is constant and realistic appreciation for the work that is being done. Day to day life can become monotonous and dull, almost to the point where fulfillment is forgotten and so is the reason why they stay in a company in the first place.
If you wish your employees to live healthy and fulfilled lives, which in the end will boost their morale as well as their quality of work, you need to show them appreciation for the right things that they have done. If they do not deserve high praise, encouragement is still a great way to be able to show them that the efforts that they have done so far have been recognized, even though there is still room to grow.
Appreciation is also important when it comes to growth as a human. Without appreciation, human beings can start growing tired of one another, and sooner or later, relationships can break down and connections might be lost forever.
