Handwriting. I grew up with computers, and my handwriting has always been garbage, so I just never really did much of it when I could avoid it. At some point in high school though, I began to write a lot. I think it partially started because my first job was working as a news writer for a small newspaper, and interviewing people required me to take notes. I ended up becoming the Editor in Chief of the school newspaper as well, and despite building the first website for the paper, I found myself keeping a notebook with notes. Eventually, as I started to write more and more, I found that handwriting things first made my writing a whole lot better. It was structured better, phrased better, and just all around... better. I bought a cheap fountain pen as well, and that made writing fun. I wrote my first book with that pen, and I've wrote a lot of research with my current one. My handwriting still sucks though.
