I used to always have an Office installation on my computer, whether it's pirated (many years ago)/using my personal license/using my school license/etc.
Then I got a new computer without bothering to do the installation. It was a long time before I discovered that I need any of Word/Excel/PowerPoint. And I was able to get by with Google Docs. If that's not good enough, I go to the free version of Office 365. In the rare occasions where I need the actual, native Office software for compatibility/functionality reasons, I do it on another machine I have access to. This has worked out surprisingly well.
