Me neither and I work at a FAANG.
I think a lot of those serial entrepreneurs that have never worked in companies have a very skewed idea of what it actually looks like once you're in a decent company.
Even putting all that aside, working for someone entails doing what you're told even if you don't want or agree with it. That's not how I want to spend my waking hours.
Being your own boss is a construction of the mind. If someone else is giving you money, they are your boss.
If I don't feel like making the button blue, I won't. If they don't agree with my decision, they are free to take their business elsewhere.
> If someone else is giving you money, they are your boss.
It is true in some respect, but when you're employed, you only have a single or handful of bosses. When you run a business, you have tens, hundreds, or even thousands of customers. You can say NO to any one of them when the push comes to shove.
