In my early career, I used to have crystal clear visions in my head for the products I wanted to build.

I learned the hard way, however, that there's a big, big gap between vision and reality.

It takes countless tiny little decisions executed very, very well to turn potentialities into realities. Further, what might be clear in your head from 40,000 feet, can often actually be little more than a rough sketch when you get up close.

In actuality, the people who have to execute your vision (including you) need to figure out (or at least internalize) a lot of very important details to make it happen.

Therefore, be sure to place proper value on the effort (and the people) it takes to turn exciting high-level vision into fully-fleshed out operational plans, products, and programs.

Said another way: There's a big difference between dreaming up an Airline, and designing the blueprints and construction process for a plane, developing booking systems and establishing safety procedures, hiring and leading operations teams etc, etc.

Placing proper value includes...

Meeting with the execution team regularly
Helping them to get alignment and make decisions quickly
Giving them the appropriate amount of time to do a good job
Trusting the people you hire to make decisions and be accountable
Asking tough questions - particularly to help them find the hidden assumptions, complexities, and edge cases
Demand excellence and look for rapid iteration/learning
