As many have already said in this thread, a simple plain text TODO list is one of the best solutions. In similar fashion, I also have my week schedule as text file. RSS reader is also helpful: updates, news, new content - always in chronological order and clearly visible. Thanks to DuckDuckGo's !bangs I only need to keep only a few bookmarks in my browser, so beside those few, I know every other bookmark is something to-read. Although sometimes I use also Pocket since it's build in Firefox either way. I regularly check e-mails and delete unneeded ones right away. Same with files. Not needed = deleted. And I keep them in clear and hierarchical directory structure.
