How did you start liking science?

I've personally been interested in science (especially astronomy) since at least age 5, when I first saw a book with a drawing of the planets. For other types of science, I've become interested as I've heard or read or watched TV about them; for example, archaelogy and paleontology (and in general the history of life on this planet, Earth's geological changes, the prehistory of humanity--both evolutionary and migratory--etc.) are topics that have become more interesting since college. (Why is Yosemite Valley so dramatic? Why is one town on the San Andreas Fault not subject to earthquakes? There was a TV series on Discovery Channel or Science Channel that focused on such things, and the answers were absolutely fascinating.)

So some of it is simply exposure to the right teacher or book or magazine or whatnot. Someone else's enthusiasm can be infectious, because they can highlight the specific details that they find so interesting, and those may not be things you've considered before. Medical science might be interesting because it allows you to help people and save lives. Materials science might be interesting because of the cool things you can create with it--for example, "invisibility" devices using metamaterials, transparent window coverings that act as solar cells, concrete that can heal itself when cracks occur, 3D-printed metals that are stronger and lighter than those made by casting or other traditional methods, etc.

Perhaps a bigger question is why you want to start liking science? Or are you just asking out of curiosity? Different people's brains are wired differently and/or have different chemistries, so some people just natively prefer numbers and science and building things, while others prefer words and images and creative pursuits, and still others prefer social interactions. There are jobs suitable to all three types, though admittedly they don't all pay equally well or exist in the same quantities. But that's another whole story. :-)
