This happens to me all the time when I am venturing into new territory with a language or framework I have little to no experience with and only the docs to guide me.

I can be 100% certain I found out what caused my bug, or how my code should really work. But I am iffy about taking out the superstitious and useless changes I made while I should have probably walked away for a bit... Changes that didn't help but didn't break anything either.
