Have you noticed people who seem to have made a hobby of pointing out faults in other people?
These characters never tire of gossiping and slandering other people. If they don't find a subject to pick on, they choose to gossip about celebrities.
Why is this so?
The answer lies in flaws in personality or personality disorder.
If 'A' has been raised in a family where it is usual for family members to quarrel and argue, A will also do the same without being told to do so.
How to break away from such habits?
Recognizing personal flaws is a blessing. So, if A wants to change this personality disorder, he/she can do so by rethinking about life and how one must develop aims in life and work towards it.
