Some people can not express their appreciation on others work. Some people are very easy to say so. It is because of pride or is it because of "I don't practice that, it is not my habit, it is not my way of doing work"... Is it very difficult to say so?
After a hard work, a small appreciation will boost up some motivation to do better in future. That is what i think and feel. Appreciate what people did and just say a simple one, "Thank you for the hard work! Good job! Well done! Do better next time! See, you made it! etc..etc.." Is it so difficult to say so? (Maybe it is for some people)...
Only a crazy thoughts after some experienced working with various types of people and my kinda observation at my working place. Quite interesting people to working with! Till then!
