Don’t worry about creating the perfect system
“Misdirected optimization is the root of all evil.” Tiago writes.
This is especially true of elaborate systems for tagging, titling, grouping, or cross-referencing notes so that you can retrieve them with total accuracy. Such systems are time-consuming to use, hard to remember, and inevitably flawed. In addition, they actually make it harder for you to spot new connections between notes by locking you into your past thinking.
