Computer SSD can hold more books than all books you ever saw in your life. saw, not read, saw in movies, saw in photographs, saw in magazines. all that can fit into your SSD So just make freaking daily journal. there is plenty of space. You will be surprised what everything you did forgot. you will be surprised how your brain worked few years back. etc etc And computer can hold more and retrieve faster then any other mechanism. Also most wealthy people i know have their own "CRM system", where they note contents of phone calls, meetings etc, it is even easier with current state of AI/ML transcription services. They note names of children, spouse of their business partners. Hobbies, life situations, birthdays.... and they WILL look you up, right before you enter their office for joint meeting, so they can have conversation with you...
