When working on solving a problem or a bug, if you find something else that's broken, ignore it.

Not forever, but to keep the focus tied to what you are working on. Get done with what you are doing and then get back to what you think needs to be fixed.

A really simple way to do this is to add an immediate `TODO:` comment in there but if you are someone who's super organised, create a note of it and get back to the original task at hand.
