I would start by finding the best online communities of DIYers and read everything you can. If you're near a big city, you can probably find IRL groups to check out. You can do anything alone, but you can accelerate the learning process by collaborating or, better yet, finding a mentor. You didn't mention your present circumstances, but a good university will help immensely with this type of field. You can also make a lot of contacts if you go to the right school. With all of that said, I'm not sure how far you can go if you aren't truly interested in it. Just keep trying different things, giving each a respectable amount of effort, and eventually something will strike a chord with you and you'll know what you want to do.
