my journal code
;;; my-diary.el ---
;;; Commentary:
;; My daily diary, inspired by org-journal, but customized for my needs.
;;
;; My keybindings: H-j to open the diary file (global binding), then
;; H-j to add an entry (local binding). C-c C-b, C-c C-f to move days
;; (like org-journal). H-i to search previous headings for completion,
;; so that I can reuse headings and then analyze them.
;;; Code:
(require 'org)
;;; Configuration variables
