You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on tbe other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Are you still in a wonderful mood? Impossible!

Communieating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.

Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others' pity or respect.

When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the knife of a negative person is put in you, you have the heavy feeling that, all in all, brings you down.

Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but this is to lower you to that same negative level and they won't feel ashamed of themselves about that.

Negativity often affects happiness without even being realized. The negative words of others at the start of the day can be attached to you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.
