Consistently recording logs is the importannt factor. You don't need fancy tools, a simple text-editor is all you need to have. In Emacs one has org-mode, in Vim, vimwiki, even for plain Notepad, one can easily create a time log by pressing the F5 key. It will fill in the time and date automatically. Create a text file like day_log.txt, open it at the start of your day and press F5 key to fill the date and time. Just add couple of words on what you want to note. Done.
