Gotta have a system, and it's likely you're the only one who can build one that works well for you. I started over 5y ago with a bullet journal (quad-ruled moleskine cahier notepads and a pentel graphgear 1000 mechanical pencil) which tools I still use daily and recommend. The "Tools for Thought" communities on Twitter and Discord are great resources too. For digital tools I spent a year using Roam but switched to Obsidian.md maybe 18 mo ago and love it. Obsidian's Discord is friendly and helpful, v highly recommended. Good luck!
