The point of data engineering
The number one thing that keeps getting hammered home to me, by experience and the folks at work I'm responsible to, is that the point of data/analytics engineering is to generate value for the business.
New pipelines and data sources don't inherently create any value. Usually, they're a net loss. Doing your own job well isn't enough: you need to make the data easy to access and use, and deliver it to the right people at the right time. Every data engineer should be at least a little bit of a data architect, too.
