I used emails to self for notes. Tried Evernote, OneNote, Keep. The problem always was: it is a separate app/page, more actions are needed than just writing an email. But since Google added three buttons and panel at the right of GMail web interface with tasks, calendar and Keep - that problem is gone. It's also possible to attach an email to a task or note, and tasks with notifications go automatically to the calendar. I still miss some features from Keep, e.g. richer formatting or markgown would be nice, but the main friction is gone and I use tasks and Keep quite regularly. For work I use StickyNotes in Windows, one per projects. Before that it was just notepad, but StickyNotes have richer formatting (than nothing) and autosave.
