She loved the book and could not speak highly enough about its impact on her life. Then, four weeks later, during a similar conversation, she stated how she did not like the book. 

What happened?

During that time, she had talked with several other people who I knew disliked it. Her opinion changed because of her friends. Her attitude went from good to bad, all because of the people she spoke with about her reading.

There is a warning in this experience. Whenever I have a bad attitude toward someone or something, I have to ask myself, “Do I feel this way because of my own thoughts and encounters, or am I adopting my feelings from someone else?”

But I really want to flip this concept over and see the good in our adopted attitudes. You also have the power to influence the people around you for good. If you always speak positively about that person, others may adopt the same attitude. If you speak well of that place or that activity, you can sway the emotions of others. If you shine a positive light, others will begin seeing what you see. 

I like venting my frustration to others and forget how it impacts their views. Each one of us can use that same power for good and bring joy instead of gloom.
