Optimism has been proven to be a pwerful positive force in people's lives. optimistic people are usually less stressed out, they are more outgoing, they work to acheive the goals they have set for themselves, knowing that they will be able to reach them. while optimism and delusional thinking are often confused, optimistics don't care because those comparing optimism to delusion are too cynical to be happy. Dr. Emoto did a study showing that words can have physical affects. when two identical bowls of steamed rice were set up by Dr. Emoto, and he said something kind each day to one, and something wrong each to another, the bowl that was spoken to kindly stayed fresh much longer, while the other rive quickly became moldy and gross. the same affect has been applied to snowflakes, and finally negativity strikes humans just as it does rice and ice crystals, but be optimistic, and you are sure to live a full, happy life.
