Measure Progress With Small Demonstrations

"I studied for 40 hours" tells you almost nothing about skill. You might have spent those hours highlighting text, re-reading the same pages, or watching tutorials on autopilot. The only honest measure of progress is demonstration: what can you do now that you couldn't do before? "I can now solve problems of type X without looking anything up" — that's real. "I can cook this dish from memory" — that's real too.

Build small demonstrations into your learning routine. Every week or two, test yourself with something concrete. Don't measure input — measure output. Write something without notes. Build something without a tutorial. Explain a concept to someone who doesn't know it. These moments of truth reveal your actual level far more honestly than any hour count ever could.
