We are living in a society that no matter what, people will always talk or have something to say...
If you do good, people will talk, if you do bad, people will also talk... After all the mouth is meant for talking.
The best way to survive is by not allowing the negative things people say to you to sink deep into you. That doesnt mean you should not take corrections, but just constructive ones.
And if you must say something to anyone, let it be something that will build the person rather than tear the person down! Spread the message.
