I have learned that the more adamant I am that something is not my problem, the more likely that I will need to fix the problem.
The worst case of this was when I was working in embedded software. I found out that the feeder mechanism was wrong, the physical, mechanical part. I was convinced this was not my problem. The mechanical engineers clearly needed to fix the equipment. When all was said and done, I was asked to, and did, fix it in software.
I now try to remember that when you point the finger at others, three other fingers are pointing back towards yourself.
