Did you ever think how much the daily words and thoughts affect your happiness?
Bad news starting in the morning. Later in the day you hear people complaining. In between you give attention to your thoughts of worry. On the way home you hear somebody telling a bad story. At home you watch a movie about people killing other people and you end the day with some more bad news.
Now let's imagine another routine. You get up, read some inspiring quotes. Be grateful for what you have. Later you meet people complaining. You smile and ask them "what good did you experience today?". "For what are you grateful today?". Worries come and you smile. I will win this game! And come to the next level. Somebody you know, tells you a bad story. You ask: What is the good in the bad story? "How can you benefit? Also, tell me something good you experienced today!"
Everywhere there is negativity waiting to enter our system. People do not notice! Be on guard, be aware. Once you are aware you can block it.
