Positive thinking

Positive thinking and optimism are great contributors to happiness. Here are some quotations on positive thinking which I particularly like:

"Think great and positive and empowering thoughts, consistently and persistently, and the reality of your life will follow suit." ~ Ralph Marston

“Supposing a tree fell down, Pooh, when we were underneath it?' 'Supposing it didn't,' said Pooh. 'After careful thought Piglet was comforted by this.” ~ A.A. Milne

"Once you replace negative thoughts with positive ones, you'll start having positive results." ~ Willie Nelson, Singer and Songwriter
