I get waylaid down rabbit holes as I work on the computer. Everybody is probably familiar with this - you start a Chrome tab to read about space exploration and two hours later you have 50 tabs open, the current one being about the nesting habits of robins :-)
A couple of years ago I started using the Evernote web clipper to save all these articles to my Evernote library. So now I don't go off track and I don't spend endless hours reading articles that are interesting but unrelated to my current projects.
My brain's FOMO related to not reading these articles appears to be satiated as long as it knows the article is safely saved in case I need it later!
