A positive attitude begins with a healthy self-image. If you will love the way you are and are satisfied, confident, and self-assured, you also make others are around feel the same way.
A negative attitude, on the other hand, has, of course, an opposite effect. So, carrying a negative attitude has a twofold drawback. You feel bad about yourself, and you make others feel the same way.
If you want to have a positive attitude, you have to feature healthy thoughts. This is probably very hard to do nowadays since, all around us, the media feeds us nothing but negative thoughts. A study shows that for every 14 things a parent says to his or her child, only one is positive. This is truly a saddening thought.
If you want a healthier outlook in life, you need to think happy thoughts, and you have to hear positive things as well. So, what can you do? Well, for starters, you could see a funny movie, you could play with children, spend some time telling jokes with friends. All these activities fill you with positive stimuli, which in turn promotes positive attitude.
