Character is the greatest wealth provided to a person. We should always try to protect it in every way. If a person loses his/her money, house or business then he/she can create it with their hard work and intelligence. But when a person loses his character then it becomes very difficult for them to gain that respect and reputation again.
A person can learn from his mistakes in any phase of his life, he can get above his mistakes bit he can never never erase a black spot in his character which made him a matter of shame for himself. It becomes very difficult for him to gain that lost respect again in the society.
So it is very important for every person to protect his/her character and be always cautious about it.
