I stopped bookmarking long ago. I almost never read bookmarks, and if I still bookmark something, and never return to it, I don't feel any guilt. Such the way it is.

I, however, still sad that I don't have energy and not bright enough to do quantum computing research (I am trying, but my applications to Xanadu, CERN and LANL were rejected), and many other things. FOMO is inevitable.

But letting things go is inevitable, too.
