Time to mind map, or brainstorm, or just write it all down on a huuuuuuge piece of paper. Each one of the main options gets its own big heading, then just get all the pros, cons, time frames and, most importantly the contingency plans down for each one. Try to focus on what you know for sure about each option, rather than speculating. However, if you do know that Option 1 will definitely open another door/option down the track, include that in your pros list.

Once it's all down on the one piece of paper, go through with some coloured crayons or textas, and underline, colour in, or any other way decorate the bits that stand out to you, that have the most resonance. This will start to give you an idea of which option holds the most energy for you (ie will yield the most energetic rewards). When this starts becoming clear, you can spend a little more time investigating the practicalities of pursuing that option, and if all of that turns out to be accessible/achievable, there's your answer.

In the meantime, don't stress too much about making the "right" decision. The "right" decision doesn't depend on what the thing is that you do, but rather how you go about doing it, kwim? You can do this Limey. Just remember that sometimes we have known all along what the answer is, it just takes having a bit of a detour to recognise that's what we have yearned for this whole time.
