Dear Abdullah Nadeem,
I must appreciate you asked a question that can be guideline for many. Remember some manners are artificial like how to behave at dining table, how to dress at a ceremony, etc. Behaving good manners root from the seed of firm imaan. I advise you to study about the life of Last Messenger (Peace be upon him) and his companions. You will come to know the true dimensions of daily routine and manners.
