Most women are living in a self and societally imposed living hell, and are only too willing to welcome you into it.

As a man you are cursed to become the exact size of what you hunt. Hunt pennies and your soul shrinks to copper. Hunt kingdoms and your hands grow large enough to hold crowns. This is the law: God carved your capacity from the same stone as your ambition, and He will not let you cheat the equation. The man who fights giants dies a giant. The man who fights nothing dies nothing

You just need to take a good look at all the older people who didn't get to live the life they wanted, and it will become obvious that the causes are always the same, generation after generation:

Developed country OH&S laws need an equal and opposite reaction.
Current laws: we can get you in trouble if you do anything that goes wrong.
New law: we can get you in trouble if you do nothing (and/or put obstacles in the way of someone doing something).

@RAlexAndradeFL So brave, so bold. - like your clipping ability. If clipping could have won WW2 you would have been first jumping off the boats on D-day.

@_mattwelter Weird how we are all connected. Was just thinking about this - how it feels like a game. Don't give up in the dark times people. Have been bouncing off rock bottom for 5 years then was here for dinner the other day with a $100+millionaire.

@shaneparrish Good for self management/AI management, bad if you are a choleric self driven personality type subordinate.

@buridansridge A wonderfully worded interpretation of uncle Maverick's "don't think, just do".

I got so sick of data stupidity I named a company after it.

Shopify CEO Tobi Lutke explains Goodhart’s law and why he doesn’t like KPIs or OKRs

“Goodhart’s law is real. The moment a metric becomes a goal, it’s no longer a useful metric… No metric by itself is a complete heuristic for a complex business. There’s a million different tensions in a company, and you can’t keep all of them in harmony by optimizing for one thing.”

For this reason, Shopify doesn’t use KPIs or OKRs. But as Tobi explains, this doesn’t mean they don’t value data and metrics.

“We are extremely data informed. We have invested enormous amounts of money and time into systems that give us basically everything at our fingertips… But what Shopify attempts to do is just not over-fit for what’s quantifiable.”

People love optimizing for highly-quantifiable things because there’s immediate gratification that comes from seeing a number go up. But Tobi thinks that the most important aspects of a product are rarely quantifiable:

“The overlap of the most valuable things you can do with a product and the things that happen to be fully quantifiable are like maybe 20%. Which leaves 80% of a value space unaddressable by the people who only look at quantifiable things.”

He continues:

“Shopify is comfortable with unquantifiable things like taste, quality, passion, love, hate… The sort of deep satisfaction that a craftsperson feels when they’ve done a job well is actually a better proxy if you allow it to be.”

They then have robust analytics systems that tell the company if something’s wrong or a new rollout breaks something.

“We think about it as a cockpit for a pilot. The decisions are still made by pilots, and we think this leads to better results… I think there needs to be more acceptance in business of unquantifiable things… And then metrics take a support function.”

“Gender confused” is such a hilarious term. It’s not final year engineering. Do you have a dick between your legs? If yes, you are a male. If no, you are female.

@paulg Thinking in terms of control systems - An ability to admit overreaction is necessary before you can calibrate the feedback algorithm.
