My suggestions for higher quality is to spend more time:

1. Designing/Picking your data structures

As you begin to code, your output and data needs might change; this might need you to change the design of your structures. Some novice developers, might think 'screw it, I've gone this far already. I've already spent a few days on this. No going back now.' If more time was taken in the beginning to plan and choose, you might be able to avoid this.

2. Refactoring.

Leave yourself some time to refactor before you push a commit. Those extra few hours or day will give you time to really go through your code and tidy it up. Think of your first commit as a first draft, then do a couple of revisions before you squash and push.

Good luck.
