If you don’t have world-class strengths where you need them, you won’t be a world-class company. - Ben Horowitz

There are several different frameworks one could use to get a handle on the indeterminate vs. determinate question. The math version is calculus vs. statistics. In a determinate world, calculus dominates. You can calculate specific things precisely and deterministically. When you send a rocket to the moon, you have to calculate precisely where it is at all times. It’s not like some iterative startup where you launch the rocket and figure things out step by step. Do you make it to the moon? To Jupiter? Do you just get lost in space? There were lots of companies in the ’90s that had launch parties but no landing parties. “But the indeterminate future is somehow one in which probability and statistics are the dominant modality for making sense of the world. Bell curves and random walks define what the future is going to look like. The standard pedagogical argument is that high schools should get rid of calculus and replace it with statistics, which is really important and actually useful. There has been a powerful shift toward the idea that statistical ways of thinking are going to drive the future.” — PETER THIEL

The Struggle is when you wonder why you started the company in the first place.

The Struggle is when people ask you why you don’t quit and you don’t know the answer.

The Struggle is when your employees think you are lying and you think they may be right.

The Struggle is when food loses its taste.

The Struggle is when you don’t believe you should be CEO of your company. The Struggle is when you know that you are in over your head and you know that you cannot be replaced. The Struggle is when everybody thinks you are an idiot, but nobody will fire you. The Struggle is where self-doubt becomes self-hatred.

The Struggle is when you are having a conversation with someone and you can’t hear a word that they are saying because all you can hear is The Struggle.

The Struggle is when you want the pain to stop. The Struggle is unhappiness.

The Struggle is when you go on vacation to feel better and you feel worse.

The Struggle is when you are surrounded by people and you are all alone. The Struggle has no mercy.

The Struggle is the land of broken promises and crushed dreams. The Struggle is a cold sweat. The Struggle is where your guts boil so much that you feel like you are going to spit blood.

The Struggle is not failure, but it causes failure. Especially if you are weak. Always if you are weak.

Most people are not strong enough.

Every great entrepreneur from Steve Jobs to Mark Zuckerberg went through The Struggle and struggle they did, so you are not alone. But that does not mean that you will make it. You may not make it. That is why it is The Struggle.

The Struggle is where greatness comes from.

The customer only knows what she thinks she wants based on her experience with the current product. The innovator can take into account everything that’s possible, but often must go against what she knows to be true. As a result, innovation requires a combination of knowledge, skill, and courage. Sometimes only the founder has the courage to ignore the data;
