Skills
Speak for 20 minutes without notes
Speaking for 20 minutes without notes is a trainable skill, not a personality trait. You get there with structure, memory anchors, rehearsal under pressure, and deliberate pause control. Most people fail because they memorize wording instead of ideas. Memorize the map, not the script, and your delivery becomes calm and flexible.
Solve a Rubik's Cube in under 30 seconds
Sub-30 on 3x3 is a serious but achievable speedcubing benchmark. You get there by mastering CFOP basics, improving lookahead, and cutting pauses between steps, not by chasing advanced algorithms too early. Most solvers stall because they overlearn algs and undertrain turning efficiency and F2L flow. Structured daily practice usually beats random long sessions.
Type 100 words per minute
The average person types around 40 words per minute. A hundred puts you in the top few percent. You don't get there by typing more. You get there by never looking down, learning the keys your fingers avoid, and fixing the few words that wreck your rhythm. Accuracy comes first, because every correction costs you more than the speed it saved.
Reach a 2000 chess rating
A 2000 rating puts you above roughly 95% of rated players. You don't get there by learning more openings. You get there by not hanging pieces, calculating two moves deeper than your opponent, and converting winning endgames you currently throw away. Tactics and clean technique beat opening theory at every level below master.
