Too many interests - not linked in

[anapana]

How can I integrate an maximise the benefits of having Bachelors and Masters degrees in a subject I have hardly used for paid work (Sociology), although I like writing in related fields. Most paid employment I have done has been teaching ESL/ESOL - as well as Admin and Legal court clerking. However much of my interests including natural/holistic medicine still not been developed -though I did some study in that. Getting too old to connect it all, but how to merge them in a positive way?
