We spend a lot of time doing busy work that's part of the process but doesn't actually move the needle. We write a lot of code that manages abstractions, but doesn't do a lot. All of this busy work feels like progress, but it's avoiding the hard work of actually writing working code.

We underestimate how inefficient working in teams is compared with individuals. We don't value skill and experience and how someone who understands a problem well can be orders of magnitude more productive.
