Paulet Biedermann says: Saying Thank You after receiving an award is very important
Receiving an award in your field and specialty area is one of the most important honor. People often forget to send a thank you card or note to the awarder. This is a way of saying I really appreciate your recognition. Because a lot of people dont take the time to do this, by sending a thank you note/card, you continue to build on your reputation as a leader.
It could be as simple as a one liner that reads Dear.....Committee, I would like to extend my sincerest gratitude for recognizing and appreciating my work. Like may others, I always do my best and expects nothing in return, albeit, your thoughtfullness means a lot to me.
