Go through the motions of reviewing your own code separately from writing it. IOW, have a code review tool such as Github or Gerrit and create a PR or change request. Then review your code similar to how you might proof read a paper. I find just the change of mindset and looking at the code in a different context (the diffs in a browser window instead of the code in your editor) helps me to catch mistakes. I usually do this for changes before I have someone else review them anyway. Of course ideally someone else could review the change but if you don’t have someone you don’t have someone. The main limitation here is that while this should help you with bugs, it’s not good for catching things which aren’t idiomatic or having someone point out a better way to do something. But it’s better than nothing.
