What is something unsexy that you should do?

So recently I came upon a blog post that pointed at this fact: The web is filled with blog posts on life hacks, tips, techniques tools on all sorts of topics; yet we rarely see the humble craft of touch typing mentioned as a item on listicles.

This seemed astonishing since it's something I and the blog author use every day - but it has few proponents.

What other similar unsexy but useful tools - physical, cognitive exist?
