Ask HN: How did you build up your personal knowledge base?
I realize this may not be the place for this comment, but a few of these comments got me thinking.Human memory is squishy, and that's great. You retain facts + feelings that help you make future decisions and everything else is integrated into smaller and smaller summaries until it fades away entirely. I spent years clinging to every experience wanting not to forget anything, and being horrified when I couldn't remember. I documented everything. I wanted my memory to work more like infinite dropbox storage and less like a tool, evolved over millions of years, to keep me safe and making good choices.These days, my personal knowledge base is whatever I've bothered to remember. Usually I don't know I've kept something tucked away until I'm in the middle of a conversation and realize it's still there. My memory of events shifts and degrades over time, and I'm fine with that.If you don't use a tool to document every page you visit and every thing you read or learn, that's completely fine too. It all fades away eventually, and if it remains relevant enough you'll hold on to the important bits.The real power-up isn't keeping it all, it's being able to  change and grow, with just enough focus on the past to make good choices.
