Regular expressions fall into this category. While they might take longer to master, you should know the basics after an hour. I've been surprised at how often people convert long lists line-by-line. You can sometimes take what was a multiple-hour task and complete it with a handful of cryptic characters.

#594On the contrary, it has taken me years to unlearn compound interest. When you start with relatively little, compound interest is relatively very unhelpful - it compounds wealth and benefits people who have started with something more than you. Twice as good at nothing is still nothing.
One of my favorite Charlie Munger speeches seems relevant [1]. > I have a friend who carried a big stack of linen cards about this thick, and when somebody would make a comment that reflected self-pity, he would take out one of the cards, take the top one off the stack and hand it to the person, and the card said, “Your story has touched my heart. Never have I heard of anyone with as many misfortunes as you. Sure, yo…

Similarly, Excusez-moi; parlez-vous Anglais? is how you get a French person to speak English.
The full handshake sequence is usually longer that this. They will first reply with "Non", often coupled with a wounded look. Then you have to start speaking in a very broken French, ideally with a monstrous accent (though this comes naturally). And only then they will suddenly re-discover their long forgotten English skills, which will turn out to be quite decent.
I think "Comment apple two" is a great opener for this.

#596You cannot master meditation within one hour, but you can learn the skills you need to begin your practice.
With six guided sessions of ten minutes each you can be well on your way to a more focused, less anxious, and happier life.
My recommendation would be to find a practitioner near you, or use one of the guided practice apps like Headspace or Calm.
Good luck on your journey.

> So much more useful! The only cables I really deal with are network cables and extension cords and I've always just done the wrap-around-your-palm-and-elbow-method. What am I missing out on?
You are missing out on what the previous comments and links are telling you -- you're twisting your poor cables to death.

#598Learn how to sharpen a knife or chisel or axe or other tool. Suddenly every piece of hard steel turns into a tool when you know how to get it sharp. All you need is some abrasive (e.g. sandpaper at 600 and 2000 grit) and a piece of leather to strop it (optionally some chromium oxide or something for honing compound). Then you can level it up from there and learn how to heat treat steel (you'll need a blowtorch) and y…

#599How to properly wrap cables. A/V and cable techs are super anal about this and it takes just a few minutes to learn, it will change your life. Cables should never be coiled in the same direction. It creates kinks when unwound and make it extremely likely for knots to form (ever leave your headphones in your pocket?). If a cable isn't being installed permanently it should be "wrapped" using a technique called "over-un…

#600CPR/Choking/First Aid course is probably close to an hour. How to change your own oil - probably lots of other money-saving home and auto DIY things... Speed reading and memory tricks can be a multiplier on learning other skills. How to use automation tools like Zapier and IFTTT - again, a force multiplier.

I've always been under the impression that for people living in multifamily housing, changing oil yourself isn't an option. It isn't "your" driveway (everyone else parks their car in the same garage), and I've never seen anybody do it. Lease terms might actually prevent oil changes, but I haven't confirmed that any place.
