I have decades of experience, but there’s often stuff I can learn.

Here’s an example: I have developed an SDK, with heavy documentation, but I have found that written docs aren’t actually very useful, as no one reads stuff anymore.

So a new engineer on my project showed me Postman. Before, I’ve used far humbler REST explorers. In turn, I showed him Charles Proxy.

I’ve actually gone way beyond what he needed with it, because it’s a great tool.

It is not a 100% replacement for my docs, but it will help a lot.

I can develop an architecture that is way beyond anything he can do, but it’s worthless, if he can’t write stuff that uses it.
