Every time you smile at someone, it is an action of love, a gift to that person, a beautiful thing. ~ Mother Teresa
September 13 is Positive Thinking Day, motivation to look forward to good things.
Your thoughts directly impact your mood, attitude, and behavior. Negative thoughts tend to create bad moods, bad attitudes, and unsuccessful behaviors. On the other hand, positive thoughts lead to positive actions and positive actions lead to positive outcomes. This is why it is important to keep your thoughts positive and focused on the things you want in life. The repetition of positive thoughts – or affirmations – will literally change your brain and help you create the life you want.
And there is a website dedicated to Positive Thinking Day to help you out. (It hasn't been updated in a few years but I'm positive that Positive Thinking Day has enduring values from year to year.)
