I feel you! My motivation is to develop medical device prototypes. I've had considerable luck so far. My friends and i developed a gait analyser for the paraplegics with an electrical simulator that could enervate their affected muscles. The current way that this works is most of the equipment is manufactured abroad and becomes too expensive For people who live for less than a dollar a day. There are so many problems that could be solved and automated. Which would be easier to go about if i knew what conceptual knowledge is imp . Thanks
