Conectarte on your own priorities:

A boy went to the Principal  and said "Madam, I won't be coming to School anymore.”
The Principal  responded “But why?”
The boy said “Ah! I saw a teacher speaking bad of another teacher;  You have a Sir who can't read well; the staff  is  not good; Students  look down upon  their fellow students and there are  so many other  wrong things happening in the Schooĺ”
The Principal  replied “OK. But before you go, do me a favor: Take a  glass full of water and walk three times around the School without spilling a drop on the floor. Afterwards, leave the School  if you desire.”
The boy thought : Now that's too easy!
And he walked three times around as the Principal  had asked. When he finished, he told the Principal  he was ready.
The Principal asked “When you were walking around the School , did you see a Teacher speaking bad about another Teacher?”
The youth replied “no.”
“did you see any Student  looking at other students in wrong way ?”
“No”
“You know why?”
“No”
“You were focused on the glass, to make sure you didn't tilt it and spill any water. It's the same with our life. When our focus is on our priorities , we don't have time to see the mistakes of others.”

*Moral of the story:*
We should concentrate on our priorities and not on others' mistakes.
