Always be the first one to review your own PR's! While it has some strong "I'll read that email I just sent from the sent folder to see it from their perspective" vibes, I've lost count on the number of times where I've spotted some obvious mistakes that I never caught while working on the code, or compiled the commits into a PR.
@anderseknert What's nice about reviewing the PR in a change control tool rather than in your IDE is it forces you to read your code in a different way than you wrote it. Similar to how printing out a document makes it easier to find typos.
