(1) Negative thinking focuses on problems rather than looking for solutions and can even create a sense of helplessness or frustration. A negative mind mostly complains about situations, people, or life itself without showing any kind of will to solve problems or effect change.

(2) A negative mind most of the time expects the worst outcomes and orients itself toward conceivable problems rather than opportunities. And if you think things will go wrong, you may unconsciously act in ways that make this happen: negative expectations can lead to negative outcomes.

(3) A negative mind will always tend to shift the blame onto others for their problems or mistakes and seldom take responsibility for one’s actions. This strains relationship since it leads to criticism, blame, and conflict features that wear down interaction.

(4) You will always find a negative person saying that they are victims of circumstance, believing that they have no control over their lives and that others are responsible for their unhappiness. They promptly judge or criticize others, mostly pointing out their flaws and faults as opposed to strengths and successes. 

The time spent with such people often leaves you feeling drained or down, since their negativity is contagious. Setting healthy boundaries in place can help safeguard a person’s well-being while still supporting others.

It is also very important to avoid negative people to maintain your mental peace and well-being.

A) Have a gentle yet firm manner of stating your need for space or boundary. An example would be, “I need some time to myself” or “I would not want to discuss anything negative”.

B) Lessen interaction with negative individuals. For those who are coworkers or relatives you couldn’t help but steer clear of, interactions would be strictly professional or when it would be absolutely necessary to do so.

C) Unfollow or mute all those negative people on social media who just post negativity and comment negatively.

D) Avoid discussing topics of a negative nature. You can respond with neutrally phrased comments like, “I’m so sorry to hear that.” In most cases, you won’t need to further contribute to the negativity. OR If the conversations are not going your way, usually ending up in negativity, try to steer them back toward more positive or at least neutral subjects.

E) Learn to express yourself and your needs with confidence without feeling intimidated or at fault; never stay ‘yes’ to all situations and requests that hamper your mental peace.

Changing the negative mindset to a positive one involves a very long process, and for that, one needs to put in continuous effort and patience. You as human beings cannot change others’ people. Then, the only option you are left with is to avoid negative people to maintain your own mental peace and well-being.
You diffuse much of the negativity through the creation of positive space, healthy boundaries, positive communications, and activities that uplift you and others. Remember that change takes time, and even small actions, when performed regularly, can cultivate a more positive, enriching environment.
