Thanks for the kind words Lauren! I added some extra information on what I perceive to be the difference between 'superficial thank you' and 'deep gratitude', and I added a funny picture, I hope this is what you had in mind. Let me know if there is any question or anything else helpful you can think of.
The part I added:
"By differentiating superficial and deep gratitude, I mean the difference between saying the every day 'thank you' and actually expressing meaningful thanks, explaining why is the contribution important, unique and what is its impact. I feel that simply saying the superficial 'thank you' does not have the same emotional effect, maybe because we say it too often and we say it every time someone did something for us, therefore it does not differentiate and it does not mean a lot anymore. If everyone says 'thank you' every time, that means that we cannot tell if the person saying 'thank you' is doing it because this is the norm, or because he or she feels grateful.
On the other hand, reading the research results I am not sure, maybe even saying the superficial 'thank you' is something that is missing from most workplaces? I would be curious to hear about other people's experiences in the comments."
"How often do you express deep gratitude, where you explain why the contribution you are thanking is unique, why is it meaningful to you, what is the impact of it? How did the recipients of the gratitude react to it?"
