I don’t like to admit mistakes. I think most people are the same way.
So none of us like to admit what we’ve forgotten. If we forget enough things, we start to forget what we’ve forgotten.
If it’s something I want to remember, I need to write it down. And if it’s worth keeping, I’ll eventually come back to it. Which means I’ll probably have to do some occasional reorganization of what I’ve written. Again, if the information is worth keeping, I’ll come back to it and it will be worth the time to reorganize.
It took me a long time to realize this. I thought it was just me, until I started to notice how few people keep notes on anything. And how much people struggle to recreate or rediscover information which I know they already had.
Write it down.
