A teacher pulled a long stain on the blackboard. Now, for all purpose, he asked: - Who can reduce this stain? But the condition is that you can not remove it !! Do not wipe it down! Then, the students expressed their inability. Because, there is no other way to reduce the stain without removing them!
This time the teacher pulled another scar below the stain, which is a little larger than the previous. Well, the previous stain was reduced without deleting!
If you understand the teacher? To make someone smaller or lose, without touching them! Make yourself grow, develop, then do not criticize others by criticizing / making bad, if you grow older then he will become small !!
