It's important to update your system regularly, to pick up security updates. This should ideally be automated.
But if you could only update one thing, I think it should probably your browser. It's exposed to data from a huge range of sources and regularly has nasty bugs.

Using spaced repetition apps with 1Password to help you memorise passwords without storing them in plaintext: https://boinkor.net/2018/11/memorizing-passwords-with-anki-1password/
Cute idea, although ideally a password manager minimises the memorisation necessary. It's a nice example of composing apps though.
Twitter treats #foo and $bar as special syntax due to emergent behaviour of users.
I keep seeing similar emergent features in other domains, e.g. airport wifi using '_Foo Wifi' to ensure it's sorted first. Ideally there'd be a priority flag, so a printer is never shown first.
404 pages are an underappreciated opportunity to serve users. If I visit a /foo-bar-baz URL that doesn't exist, ideally the site would search for content matching foo, bar or baz rather than just displaying 'sorry' or a pun.
