For my upcoming book: what has philanthropy given back to you, personally and professionally?

In my book, “Amp It Up! Secrets from Science for Creating the Life of Your Dreams,” I am devoting a chapter to the concept of two-way gifting.  It is my premise that people can receive benefit in both their personal and professional lives through their involvement in causes that they identify with but which are outside of themselves.  What benefits have you received because of your support of causes?

Thanks for your feedback! –K.
