Look for solution not for a guilty

When facing a problem look for a solution not for a guilty.
There are two basic ways of facing problems, one is to look for the guilty. Who was?!, the other is to try to solve it.
In a higher porcentage than what it should happen we look for a guilty. This don't solve the problem but make it worst. When you find the guilty what you're going to do?. To beat him/her?.
Any person than make a mistake feels enought embarrass, he/her doesn't need to be point to or anything else
To look for a solution has a very high probability of solving the problem (if it's possible), besides it's given the posibility of learning if it was a human fail and don't encourage feelings of shame and guiltyness....
