Trying to Memorize What You Should Understand — and Vice Versa

Some things need understanding: concepts, principles, systems, cause-and-effect relationships. Others need plain memorization: vocabulary, dates, formulas, names. Using the wrong strategy for the wrong material wastes enormous amounts of time. You can't memorize your way to understanding physics — you need to grasp why things work. And you can't reason your way to remembering a phone number — you just need to commit it to memory.

The skill is recognizing which is which. Ask yourself: can I derive this from something I already know, or do I simply need to remember it? Concepts need explanation, examples, and connection to what you already understand. Facts need repetition, mnemonics, and practice. Matching the right tool to the right task saves time and frustration.
