Is it possilble to sail from India to the USA in a straight line?

Yes, provided you know what's a geodesic, or the shortest path (arc) between two points on a sphere, analog to a "straight line" on a plane.

How to spot high agency people:

1. Weird teenage hobbies - Teenage years are the hardest time to go against social pressures. If they can go against the crowd as a teenager, they can go against the crowd as an adult.

2. Energy distortion field - If you meet with them when you're tired and defeated, you leave the room ready to run a marathon on a treadmill with max incline. Low agency people do the opposite.

3. Golden question - If you're in a 3rd world prison cell and had to call someone to get you out, who would you call? That's the highest agency person you know.

4. You can never guess their opinions - The boxer that writes poetry. The advertiser obsessed with the history of war. The beauty queen who reads Nietzsche. If their beliefs don't line up with their stereotypes, they've exercised agency.

5. Immigrant mentality - If they've moved from their hometown, that's a good sign. If they've moved from their home country, that's an even greater sign.

It takes agency to spot you're in the wrong place, resourcefulness to operationalise a move and a growth mindset to start from zero in a new location.

6. They send you niche content - Low agency people look at the social engagement of content before deeming its quality. High agency people just look at the content. They spot upcoming trends very early.

7. Mean to your face but nice behind your back - The social incentives are to be nice to people's faces and gossip behind their backs. To do the opposite requires agency because they're swimming against the social tide.

This is the International Fixed Calendar (IFC).

It splits the year into 13 months (each with 28 days). And the world was very close to adopting it in the 1930s.

Compared to the 12-month Gregorian calendar, IFC is much simpler:

▫️ Calendar is same every year
▫️ Each month has exactly 4 weeks
▫️ Every month starts on Sunday and ends on Saturday
▫️ Every date of every month is the same day (“16th” is a Monday)

The 13th month was called “Sol”, as the extra month fell between June and July, around summer solstice.

You’re probably thinking “28x13 = 364” (and “I’m learning way more about calendars than I expected today”).

To address this — and to get to 365 days — the IFC added a one-day world holiday (“Year Day”) between the last Saturday and Sunday of the year.

Kodak founder George Eastman was a fan of IFC and used the calendar for Kodak reporting. Eastman even convinced 100+ other companies to do the same.

Kodak kept the IFC from 1928 until 1989.

Why? Every month had the same number of days (and weekends), making it easier to compare income statements across months and years.

Perhaps unsurprisingly, the IFC was the brainchild of an accountant (a British dude named Moses Cotsworth).

The IFC was ultimately scrapped.

Religious bodies couldn’t agree on standardizing certain dates (e.g. the one-day world holiday would change which day the Sabbath fell on every year; there was no agreement on Easter).

The business community also realized that existing bonds and contracts — using the Gregorian calendar — would be a pain to update.

Days and years follow the logic of the solar system. Months are way more flexible, and that’s how we almost had the IFC.
