Appreciation is a way of encouraging someone in life, it's a state of portraying your remorseful feeling to others telling them that you truly love what they are doing or what they've already done.
Appreciation comes in different ways,some is done when someone has done you a favor In life, while other means is when someone is doing a specific thing in life.
Take for instance you asked your son to do a certain job at home and as he was doing it,you go to him and say you are doing a great job,or weldone on the good job you are doing that's an appreciation,it clearly shows that you appreciate his effort or the thing he's actually doing,well there's so many ways in which appreciation can be used.
Appreciation can make someone go an extra mile for your sake, showing appreciate is a form of being grateful but there's a little bend between them, I don't mean they're both entirely different from each no.
One can show real gratitude in just a one stand interaction with the person that has done him/her a certain favor but appreciation is a continual thing,what i mean take for example, someone can send you money and you just tell the person thank you for the money, that's gratitude it means you are grateful for the money,but in the aspect of appreciation you will still get to call the person again to show more gratitude........well to put both together, appreciation give birth to gratitude, because it's when you find something worth appreciating that's when you give gratitude
Lets be appreciative
