Some may say you never expect good things to happen, but maybe you’re just a realist, a person who uses facts and past events, rather than hopeful feelings and wishes, to predict the future.
In art, Realist painters started a movement by depicting the world around them as it actually appeared, rather than painting flattering portraits of unattractive people and scenes too good to be true. You don't have to be an artist to be a realist — just consider limitations and anticipate that things that can go wrong will go wrong. The downside? Realists don't get to dream of the great things that could happen if everything goes right.
