Definitely a case of practice as others have said. When I first started using LaTeX I was looking things up on tex.stackexchange.com every two minutes. Once I'd gotten used to it and created a lot of documents, I was able to use it to take notes in real time faster than I could write. I now use LaTeX to take all of my lecture notes and it does a great job. I've defined a couple of helpful environments and created a documentclass along the way to set things up how I like, but it's so much faster than e.g. Word or pen and paper.
