Finding talents through giving

From The Lazy Way to Success (which has got some other interesting views on how to be successful) :

What do I give, the giving of which fills me with great bliss? Focusing on this can help to identify your calling - and as an added bonus the process is often enjoyable/fulfilling and rareley ever feels like “work.”

Another way to ask this question is - what type of work have I received compliments on? What did I enjoy about it? How can I turn that into the focus of my job?
