Pattern
Your open tabs should be only what you're working on now. Anything for later belongs in a separate read-later list.
Practice
Close tabs that don't belong to the current task and move genuinely useful future material into a separate read-later list.
Start small
Choose one browser window and close tabs unrelated to your current task, or save useful ones to a read-later list.
Watch out
A read-later list can turn into another pile that never ends. Go through it or clear it out now and then.
Concepts
- zero queues
- Things like your inbox, open tabs, or a watch-later list have a clear end, so they can be empty again.
