You are appreciated!
It can be pretty easy to feel unappreciated in this business, but know that you are touching a lot of people. Without you, companies would not have a pulse on what they're customers think about a product, food item, or whats not working. It takes a certain person to be able to do this job and you my friend you are it! Just think, your president or CEO would not be able to do this day in day out. They need you!
Wtf?
