I kept a journal that included learning and so much more from 1968 to 1982. I stopped because I came up with something better. A milestone list - using associative memory cues. Initially it was typed out. In the early 1990s when I bought my first computer a Mac - originally owned by Bobby Weir of The Grateful Dead: I transferred it to an Excel Spread sheet.
Thinking about thinking includes part of the picture. Associative memory helps trigger all sorts of past memories filled with aromas, a cornucopia of emotions and spiritual epiphanies.
PS I make it a point -- when a group or a person follows me to read a piece. Thanks for connecting and edging into the community of people connecting. Connectors is a much better word than followers - don't you think?
