The negative mental filter can imply the following:
• A situation where someone sieves the little negative from a situation and dwells on it, forgetting about the positive aspects completely.
• It causes someone to hear a half hour of praise after a job evaluation but leaves the meeting depressed because of one area needing improvement.
• Sometimes the little negative comment you hear from one or two persons may even be because such a person is jealous of your great achievements.
• Choosing to focus only on the negative causes mental stress
Having a negative filter makes it difficult to accept sincere praises or compliments.
Try to gracefully accept praise or compliment when rightly given. It is not a sign of pride , it would help you enhance positive energy.
