I have been seeking to develop habits / follow a system to increase code quality, both in terms of readability and number of functional issues. I have come up with a few ideas I have listed below but I am curious what other people have been trying out! Have any of the below worked for you? What specific steps do you take to ensure code quality?

1. More awareness while writing code: it's tempting to write a rough draft version of the code thinking you will polish it later but oftentimes it's easier to spot mistakes while your attention is on the erroneous line of code. Example of this in action: search for where the method you're modifying is used in the code base before making changes to it.
2. Do not submit the code for review immediately after writing the code. Give yourself a short break, come back and review your code with a fresh mind, which will make spotting bugs easier.
3. Write down the possible edge cases in a notebook before submitting the PR for review. For medium to large PRs, the process of writing itself can help you consider more edge cases than simply keeping them in your head.
