Figure out what I want to study next

figure this out for years now. My problem is that I’m interested in so many things so it’s hard to narrow down what exactly I want to study. I have toyed with the idea of doing a Dip Ed, which when combined with my current degree in Science (chemistry and oceanography) would allow me to teach science at a high school level. I have also toyed with the idea of doing my masters – possibly in project management – a topic in which I haven’t done any formal study previously, but which my current job has given me the background to do and will entirely fund. Both of these would be relatively easy to organise and fund (as my job would largely pay for both) but I don’t know if it’s what I WANT to do. My real interests actually sit in an area a thousands miles away from what I’m currently doing. The subjects of Palaeontology, Genetics, Earth Tectonics, Evolution and Volcanic Activity really facinate me. My issue is that I have no idea how to go about doing this. Last night I researched universities that teach earth science and they are few and far between. The ones that allow you to learn through distance education are even more rare! I did find one though which could be a potential option. I’m going to enquire soon and see if I can get a bit more information.
