Hypocrisy

Hypocrisy is the state of being in double standard and insincere in thoughts and actions. For a country, over population is not a problem unless it is people do not follow double standards. When every individual has two identities, it causes more trouble. To be your own self is the best help to you and for those around you. It is quite human nature to find fault with others while your own self is at fault. “All humans are hypocrites; the biggest hypocrite is the one who claims to detest hypocrisy” many religions said "A hypocrite can be identified in three ways, 
when he speaks, he speaks lies, 
when makes a promise he breaks it .. and 
when he is trusted he betrays his trust. So, Just remember two things 
one.. It is better to identify and stay away from a hypocrite.
two.. Always practice what you preach before trying to teach it to someone else.
