When someone else gives feedback on my code, it's very easy to slip into a defensive mindset. How dare you challenge my perfectly-crafted code! But over time, I've really grown to enjoy having my code reviewed.
As an example, Aaron was looking at one of my pull requests, and he commented on the name of a particular function. With the change I introduced in this PR, the name wasn't fully accurate anymore.
Instead of just brushing it off, we paired for a bit, and that simple name observation led to a really nice refactoring. In the end, the code became much more readable.

P.S. If you're a solo dev and don't have someone to do code review, I'd be happy to take a look. It's a really valuable process.
