Go through your expenses and identify waste. Even if you’d don’t keep a budget check your credit card statements etc. cancel unrequited subscriptions, haggle utility bills, refinance loans, etc.

But looking at my credit card statement gives me anxiety.

That's the point! Thinking about money should not be a cause of stress in your life. If money is stressful then budget/expense tracking is what you _need_.

Since we got married me and my wife have been tracking every expense down to the penny. The net result has been no fights about money, everything was known and obvious from the records. Every so often we come together, look at the numbers, and decide things. You might decide an expense is worth it, or you might decide an expense is not worth it. Without measurements you cannot make that decision, with measurements you are in control.

Once you are in control money should become a tool, and a source of freedom to spend on what you value.

You can learn the basics of DJ-ing on digital decks in an hour. However, it can take years of practicing to reach a level of a mediocre DJ who can lead a party with a lot of people you don't know. DJ-ing is a surprisingly difficult underappreciated skill, which can also be very rewarding when you learn it. The decks become your musical instrument on which you can modify the original music as much as you want and glue together pieces in a myriad of possible ways to build one long running non-stop musical track.

This ties in to how I like to say the rope may be one of the greatest inventions of mankind.

I find myself unravelling mentally when it comes to remembering knots and the like

That's nothing, you should see what the mathematicians get up to when they try to figure out if two knots are different.

Earlier quoted context omitted.

Simple transformations can easily become complex to do with regex, so I've started using vim macros instead.

Regex don’t do transformations? All they can do is match strings.

Regex grouping expressions along with find & replace enable transformations.

People think touch typing takes a long time to learn, and getting good does take a while, but it only takes about an hour to memorize the alphanumerics and which finger types what well enough to break the hunt and peck looking at the keyboard cycle forever. Once the cycle is broken just typing casually is enough to eventually achieve mastery. It's only that one or two hours that really suck, and then that week or so…

If you use a computer in any way in the course of your job or daily life, touch typing is the single biggest improvement in productivity and quality of life that you can make. It is SO much faster and easier than hunt and peck.

The Cyrillic script is fairly easy to learn and will let you phonetically read a bunch of languages (Ukrainian, Russian, Belarusian, Bulgarian, Mongolian, and Serbian to name a few.) Each language has a few unique letters and pronunciation can vary slightly, but for the most part they are the same. https://en.wikipedia.org/wiki/Cyrillic_script

Here's a guide to reading Cyrillic with some fun mnemonics and tips: http://i.imgur.com/bCiPTU5.jpg
