Yep. Self-reviewing your own PRs is a large boost to both yourself and the team, and often one of the first things I encourage new-ish developers to do.

- 90% of the time when you self-review your own PR, you're going to spot a bug or some incorrect assumption you made along the way. Or you'll see an opportunity to clean things up / make it better.

- Self-reviewing and annotating your reasons/thought process gives much more context to the actual reviewer, who likely only has a surface level understanding of what you're trying to do.

- It also signals to your team that you've taken the time to check your assumptions and verify you're solving the problem you say you are in the PR description.
