Be happy! I want to tell about one method. Everyone can use it. If you use it right, you will be happy! When you have a difficult situation, when you have a bad mood, when you are sad, when... just STOP! Two or three minutes you must think about nothing. Then you must start to talk yourself about you. Yes, this is not a mistake! You must start to talk yourself about you. If you are working, you can interrupt your work. The louder you will talk that greatly affect you will have. For example: - I'm very smart - I'm very beautiful - I can do everything - I have a good smile - I'm the sun (why not?) ) - I have a great goal - .... I believe you have more variants If you do it one time right, you will do it again and again =) When I do it, I'm happy. When I'm happy, I can make others are happy!
