💯 A good advice: for your first real job, strive to screen for a great manager.

I know, easier said than done. Mostly because inexperienced workers don’t know how to tell a great manager from a bad one.

Here’s some tips to do that (thread)
1/ Good managers are clear.

During your job interview, ask questions on your future tasks and career opportunities.

If his replies are vague, it’s a red flag.
2/ Ask hard questions. Why do employees leave? What do employees complain about? What attitudes he likes *and what does he dislike*?

If he gets defensive, it’s a red flag.

WHY IS ERGODICITY IMPORTANT? AN EXAMPLE

My cousin was born in a mountain village in the French Alps. Like many there, he learned to ski before reading.

I am a good skier, but I remember the humiliation when I was 14 and he was 6, seeing him surpass me, swift as a bullet.
2/ At a young age, he made it into the World Championships for his age bracket. Boy, he was fast.

His career came to an abrupt end a decade later, one injury at a time. First, he injured his ankle. Then, he broke his knee. A few more injuries later, he retired, too young.
3/ From him, I learned that the skiers that you see on TV, the fastest racers in the world, didn’t get there because they were the fastest.

They got there because they were the fastest of those who didn’t get injured into retirement.

Why should companies care about laws if, when the way they conducted their core activity is found fraudulent, the fine is just 0.5% of their market cap?

(or ~8% of their revenues, annualized using Q2/20 as a basis)
8% of revenues is a fee, not a fine

(considering that it applies to the whole core business, not to just one transaction)
The heart of the problem, IMHO 👇

A NON-BINARY VIEW OF ERGODICITY

From a mathematical point of view, a model describing an activity is either ergodic or isn't.

In real life, instead, it makes sense to describe ergodicity as a non-binary property.

Here is why.

Thread, 1/9
2/ Take two non-ergodic activities: crossing the street and skydiving.

For both, the outcome of performing them an infinite number of times is death.

However, it is intuitive to most that crossing the street is on a different risk category.

How to express this mathematically?
3/ People don't care about infinite time frames. They have limited life expectancy.

They do not care about the question, "does crossing the street have a chance to kill me?"

They care about, "does crossing the street have a meaningful chance to kill me within my lifetime?"

Interesting!

During ⚡️ usage peaks, "the folks running the electricity grid would rather pay people to use less electricity rather than pay a power plant to turn on."

So this startup pays households to shut down their appliances during peak usage.

ohmconnect.com/how-it-works/w…
Example without the startup:

1) There's an electricity demand surge (too many people use ⚡️ at the same time)

2) The "normal power generation" is not enough.
The electricity company has to spend money to power a second generator (that pollutes more, btw)

3) That's expensive!
Example with the startup:

1) The grid sees high ⚡️ demand

2) The startup messages its users, asking them to shut down their appliances

3) The startup pays them, less than it would have costed to the power plant, and pockets the difference. Everyone wins.

As for many employees this is year-end evaluation period, a reminder:

This is the moment to make a motivated ask for whatever you might need (money, time, training, trust, better projects, a career move, etc.)

FAQs below

1/3
2/ Q: Even if my boss doesn’t ask?

Yes. Some are jerks, some are parsimonious, but many want to allocate limited resources such as promotions to those who are motivated enough to ask (tip: they often use willingness to ask as a proxy to “ability to get results”).

Ask.
3/ Q: How should I ask?

Make sure you cover:
– What you will do with it (yes, even if it’s personal)
– Why should your boss believe you (i.e., past examples of good things you did for the company)
