Just throwing out an alternative: for work, I have a 230k word file of notes I've taken that I edit with emacs org mode. I add to this file 2-3 time per week (so, not every day, but pretty frequently). With org mode, you get the "folding" of different sections for free. Plus, org mode has different tools for converting content, so no need to build one-off bash scripts for many common use cases.
