I think what makes a difference is how you react when something goes wrong. Do you flip out and pull your hair out and complain? Or do you calmly try to understand what the problem is, spend some time figuring out what YOU did to create the problem and then fix it. I work with people who look in all the wrong places to fix a problem thinking some hidden magical set of code breaks things at random.
Once you realize that the clues are all in the errors and they're not just random bits of text, that's what sets you free and gives you the power to fix.
