Curate, connect, and discover
Have multiple copies of writing you really care about. You never know when you're going to have your laptop give out, or lose a flashdrive, or drop your notebook in water. This is another way handwriting it comes in handy. You automatically gain two copies: a physical one and a typed version. Even saving recent copies to an email draft is a good idea. (Or emailing them to yourself if you don't trust drafts)
