Good for you

When people find out my upcoming organ donation, I get a range of comments usually with adjectives like generosity, admirable, courage, sacrifice, etc. The one I like the most is when someone says "good for you" and typically this is often said by strangers like a nurse, technician, etc when they find out about it.  

So in my own way, I was trying to list why it was good for me and then I found this list in WaitlistZero which pretty much captures it. 

Benefits reported in the scholarly literature include

• Deep gratification in helping another person. 
• Desire to improve the recipient’s quality of life and health
• Improving their own quality of life
• Avoiding the loss of the loved one
• Improving the quality of life for the recipient
• Increased self-esteem
• Improved relationship with the recipient
• Positively influencing the lives of family and loved ones.

There is additional research on well-being/happiness that indicates gratitude can increases happiness, so there is additional derived benefit.
