In the 19th century, Hermann Ebbinghaus spent years memorising nonsense syllables and measuring how much he forgot. He discovered something that underpins the whole science of learning today: what matters isn't only how much you study, but how you spread it over time.
Studying five hours straight pays off far less than those same five hours split across several days. Every time you let some time pass and then retrieve the information just as you were starting to forget it, you fix it deeper. It's the spacing effect, and it's the basis of the repetition apps people use to learn languages.
The last-minute crammer passes and forgets within a week. The one who spreads it out remembers months later.
The lesson: don't study more hours, stretch them out. Your memory rewards patience, not haste.
