A Simple Way to Actually Remember What You Read

Writing a three-sentence summary immediately after finishing a book, before starting the next one, did more for actual retention than any highlighting system I’d tried before. The constraint of three sentences forces you to identify what actually mattered instead of restating the plot.

I keep these summaries in a single running document, oldest at the bottom, and skimming it once a year works like a highlight reel of everything I’ve read. Books I can’t summarize in three sentences are usually the ones that didn’t leave much of an impression anyway, which is its own useful piece of information.

It takes maybe five minutes per book and costs nothing, which is probably why it’s easy to skip even though it works.

A Freelancer’s Guide to Estimating Taxes Without Panic

The number that made quarterly taxes stop being scary was simple: set aside 25 to 30 percent of every single payment the moment it arrives, into a separate savings account you don’t touch for anything else. It’s not exact, but it’s close enough to avoid the panic of owing a huge lump sum in April.

I also started tracking deductible expenses in the same spreadsheet as income, logged the same day rather than reconstructed later from memory, which turned tax season from a week of digging through receipts into about twenty minutes of copying numbers.

The habit that mattered most wasn’t a clever tax strategy, it was just moving the money out of sight the same day it arrived.

The Spreadsheet I Use to Split Bills With Roommates

Three roommates, three different income levels, and a house full of shared bills that used to cause quiet resentment every month. The fix was a simple spreadsheet that splits fixed costs like rent evenly but splits variable costs like groceries and utilities proportionally to income, agreed on once at the start.

Each person logs what they paid directly, the sheet calculates who owes who, and we settle up once a month instead of constantly Venmo-ing each other for small amounts. The proportional split took some upfront conversation to agree on, but it’s removed almost all the friction that used to come with an even three-way split.

It’s not complicated, just a few formulas, but having it written down and agreed on ahead of time did more than any conversation could have.

Running Shoes: When to Actually Replace Them

The 300 to 500 mile rule gets repeated everywhere, but it ignores how differently shoes wear depending on running surface, body weight, and gait. I’ve had a pair last 550 miles on soft trail with no issues, and another pair go noticeably dead by 280 miles on pavement.

A better test: press a thumb into the midsole foam. If it springs back slowly instead of quickly, or if you can feel the ground through the heel more than you used to, that’s the real signal, not the odometer number on your running app.

I now check the thumb test monthly instead of counting miles, and it’s caught a dead pair of shoes twice before the mileage counter would have.

The Keyboard Shortcut List I Actually Use Daily

Not the exhaustive fifty-shortcut cheat sheet nobody memorizes, just the six that actually changed how fast I work: window snapping, clipboard history, quick app switching held for a second longer to see all windows, a screenshot-to-clipboard shortcut, tab reopen, and a dedicated shortcut for pasting as plain text.

That last one alone saved me from hours of manually stripping formatting out of pasted text over the past year. I didn’t even know it existed until a coworker mentioned it offhand.

Six shortcuts, genuinely used every day, beats a printed sheet of fifty I’d never reference again after day one.

A Budget Breakdown: Two Weeks in Lisbon on $60 a Day

Accommodation ate the biggest share, about $28 a day for a private room in a guesthouse near Alfama, booked six weeks out. Food came in around $18 a day by eating lunch at tascas (the workday set menu, not the tourist menu) and cooking breakfast in the guesthouse kitchen.

Transit passes cost $1.65 a day using the Viva Viagem card, and the remaining $12 covered museum entries, a day trip to Sintra by train, and one splurge dinner near the end.

The number that surprised me most: skipping one sit-down dinner a day for a grocery-store picnic saved almost exactly what the Sintra day trip cost.

Packing for Ten Days in One Carry-On (No, Really)

The trick isn’t packing less clothing, it’s packing clothing that does double duty. Two pairs of pants that both go from daytime to dinner, one merino layer that doesn’t hold odor after three wears, and shoes you’re willing to wear on the plane so they don’t eat suitcase space.

I did Lisbon to Porto to Madrid, ten days, one 22-liter bag, laundry once mid-trip in a hotel sink. The only thing I regretted not bringing was a second pair of socks; everything else got used or worn more than once without anyone noticing.

Roll, don’t fold, and put shoes in first against the wheels, everything else stacks around them.
