To make big things, you must first get rid of everyone else that don’t believe people can make big things. That’s the first step towards getting rid of that same belief inside you, and the only way you can even get started. Then you start doing things, and continue, and find a way to not get tired of it. You remove all unnecessary energy spent on things that slows this process down, and narrow your focus so you don’t end up only spending time on administrating, planning and handling the biproducts of you making what you make. You learn by doing, and by learning, and by reconsidering what you've learned from doing and learning. Repeat this as many times as you want! This will give you real experience and knowledge. Then, when you've reached your full potential (if that's even possible?), you find other people who can help you go even further. People who align with your worldview and are willing to follow your direction, but who are good at something else than you. And you let them go through the same process as you did. Then you try to remove all unnecessary communication between you and your people, so you don’t end up spending all your time handling a company, when you really should be making things. With every new person, the communication will grow exponentially, and in the end you will have an organization that by itself has gotten its own will, needs and drive. Now, you either work actively and hard to keep this complexity (bureaucracy) down, or it becomes a monster that eats you up. If you succeed, you'll be able to continue making big things for a longer time. So now, continue with this for as long as you feel like.
This post was inspired by MrBeast and his quest to use as many cameras as possible (among other things). You can obviously make big things that are nothing else than just big, by just using many people and much time, but to make big things that are big as in ”interesting”, you'll need some more thoughts and intention behind your actions.
