1) Grievance
Holding a grudge against another person in your heart weighs you down. Seeing that person with resentment, Hate will continue to follow, so it can destroy your peace of mind. That's why being jealous of a person first burns the person before it harms that person. If you know that you have such a grudge, you should try to completely remove it from your mind.

2) Anxiety
Worrying about what hasn't happened yet will ruin your present. That's why instead of worrying about what hasn't happened yet, make the most of the present moment. That is more certain. Be determined that you will try your best to face whatever happens.

3) Bad past
Same as number 2. Not being able to forget all the bad things that have happened in the past makes your mind heavy and the present time passes. Being unable to do anything and being frustrated will only waste your time. That's why you can't fix your bad past, so use the present time to make the most of it.

4) Mistakes
Like the bad past. You can't do anything about the mistakes you've already made as you sit in misery. All you can do is learn to not make the same mistake again. Only that will prevent you from making more mistakes. That's why I focus on learning from my mistakes and trying not to make them.

5) Bad people
pessimists People like bad poison on you. You forget all the people who gave you all kinds of trouble. Stay clear. If you still can't get rid of it, try to get rid of it in the future. If not, they will study your mind as far as they are concerned. Must be angry.
