Some jobs are set up that way. That’s how things have always been. There is a process of things. A system. They are designed to plug in the right parts so that it can function properly.
But then there is another kind of worker. The kind that fears his next project might fail. The kind that worries about whether or not she is an imposture for suggesting a solution to something she hardly knows anything about.
If you are standing up to the process you might sound dumb sometimes, or come across as being ignorant or naive. But you are surely on your way toward something greater. Stick with it.
