I like your idea of a ***it bucket, I've been wondering what to do with all my long running moans, I haven't liked to just delete them from my todo list.
I have also kept a daily journal for many years on computer, and having learnt that my memories will be lost roughly chronologically, I've started going through them highlighting those I can still recall (visualise), an exercise I plan to repeat annually, highlighting in a different colour each year.
I have done/am doing the same for people and places
And am planning on doing it for all the photographs of people with dates.
Partly to chart the 'progress', partly in the hope of extending/refreshing the memories by recalling them.
