I have quite a pile of notes going way back. One really old one was “(M)agreeable liquidation plan”. It is a list of all the steps to close down my one-person company, (M)agreeable software, inc. I did that in 1998 and 1999. One of the items is “Jan 1999 File final taxes”.
(M)agreeable software was one of the many things I am glad I did but glad I am not doing it now.
