What shall I do next? Listener question

I am at an in-between stage in my life, retiring from a very fulfilling and fun career as a veterinarian and looking at what is next for me.I feel I am in a place where I would like to make some kind of contribution to this world of chaos that seems to be ramping up, yet am hesitant to jump into  trying to 'fix the world’  out there that is just made up of my projections.I  do not have many limitations or restrictions on what I could do but as a result feel somewhat overwhelmed by the courses/choices/options available.Do you have any suggestions about how to go about finding the ‘right’ thing to do?
