The superior man blames himself. The inferior man blames others.
Something went wrong? Better look for a scapegoat right?
You either take responsibility and fix it or at least you try to help fixing it.
Who cares who is to blame? Problems are not solved by finding fault, they are solved by being fixed.
Fool me once, shame on you; fool me twice, shame on me.
When something goes wrong you should not start looking for someone to blame. Think about what you could have done or can do in the future to prevent sucht things.
It is not worth anything to have someone to blame if it does not provide a solution. Don’t be the hater, instead be the one who observes and comes up with some ideas to be better next time. Take the high road!
