My partner spent yesterday writing test cases for some open source code he is creating.

Some things we do are not enjoyable.

We do them because they are a step in something that matters to us.

No one is “making” him write.

He does it because that is what professionals do.

No one is making you do something, either.

Frame it as “I am doing this because I want to maintain my professional standards.”

See how different it feels.
