Writing a Thank You Letter needs to be something that comes naturally and something you do on a routine basis for a variety of reasons. Thanking people should be very easy even for the smallest of reasons. Of course taking it to the next level by actually setting down and taking the time to write our a Thank You Letter is a sure sign of a great leader. After all you by yourself can't succeed. As I continually tell my staff I must and do depend on them for my success; however, they can easily succeed without me! Therefore, I am very thankful for their service daily!
I personally think that hand writing a note in a greeting card is one of the best and most sincere ways to tell someone thank you. This is not to say the handwriting a Thank You Note or Letter is not also very meaningful. Of course everyone has a little different opinion on this subject. But regardless it is critical to take the time to write out something. It does not have to be anything complicated or long and drawn out. In fact make it short and personal.
Just a quick note to let you know how thankful I am that you got that report in on time! It truly was done professionally and addressed all the major aspects of the project!
Thank you very much for the amazing job you did to get those reports out on time! I know that you were facing some pretty tough odds but like always you came through when I needed you!
My point is that you don't need to complicate the process of a Thank Your! It should be short and to the point! It will be very meaningful to whoever you present it to!
Good Luck and May God Bless You!
