You are a person who values efficiency, there are companies that will take advantage of that and make you burnout then fire you if you don't have protections or do not live in a country that have them.
Some of those people that you noticed also someday wanted to make everything better and efficient, but they can't, because most companies follow a hierarchy that do not accept changes coming from bellow to the top.
You already noticed that you can become like this, the difference will be your values, ethics and which companies will you work for, some companies can and will make you fall into hierarchy and conformism, unfortunately.
If you are young and have that option maybe search for more flexible jobs where they will accept ideas and try things like startup's but they are often chaotic and unstable also.
I hope some of it help you, be careful to not burnout think about the long-term also.
