It’s a mark of a genius to explain complicated things in simple ways- the smartest people understand what they r talking about. Instead of just focusing on what’s important, figure out what ISN’T important and ignore it

As you figure out what works you can remove parts.  1st Question the requirements.  Eliminate requirement that aren't necessary.  Keep distilling until it becomes optimized.

If you don’t have a strong vision of what it should and should not do, then you end up with a giant mess of competing features.

Jack Dorsey has a great phrase: “Limit the number of details and make every detail perfect.” And that’s especially important in consumer products. You have to be extremely opinionated. All the best products in consumer-land get there through simplicity.

You could argue the recent success of ChatGPT and similar AI chatbots is because they’re even simpler than Google.

To be simple, you have to be extremely opinionated. You have to remove everything that doesn’t match your opinion of what the product should be doing. You have to meticulously remove every single click, every single extra button, every single setting.

What is an iteration? An iteration is when you do something and then you look at the result; you test the result somehow—ideally against a free market, nature, or physics. Then you ask, “Did this work or not? What part of this experiment worked or not?” Great people will distill insights from every iteration. 

Complexity increases because adding is easy and removing is dangerous.

Whenever there's a problem, we add: a new person, requirement, or process. We never subtract.Why? So we become professional complexity managers. Entire careers are built managing unnecessary mass. But this is the opportunity. While everyone else adds mass to the system, removing it creates an unfair advantage. The lighter you are, the faster you move. Removing what shouldn't exist creates more value than any addition could. 

You have to do the work wrong many times before you discover how to do it right.

French aviator Antoine de Saint-Exupéry on engineering excellence:

"A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.”

All the energy we spend trying to fix what's broken comes at the expense of making what already works.
