Perhaps you are not good at just one thing, perhaps you need to find a focus area where the three topics in which you are interested are combined. Robotics springs to mind.

I too feel inspired by talented people, and stand in awe of experts. Through feedback from others, I found that I was rather good in an area I would never have expected earlier, namely managing people and later building teams and running projects/companies. Perhaps your true talent lies elsewhere as well?
