When I collect words,sayings, quotes, random thoughts, etc, I usually keep them alphabetically in my journals. I set up a page for each letter and collect things for each page. It is a work in motion however, some pages fill easily, others sit empty for a long time, as if waiting for the right word or phrase. Words/thoughts/quotes are placed under the letter that fits best at the time, not necessarily under the first letter of the phrase/word/thought.
I used to hate handwriting my own notes (which seemed to always look like scribbled down notes) but now I just accept that my handwriting is what makes my journal mine. It may not look as pretty as fancy fonts, but it is mine.
Anyway, I have put this alphabet of sorts into a slide show – hope it works!
