Someone who has an attitude of pessimism is a person who usually expects the worst and who believes that bad things are bound to happen eventually. Pessimism quotes can be found that show why this negative outlook is damaging. If you find that you have pessimism then you can not see the good in your life because of the negative view of the world that you have, and this causes you to miss out on the good things that life offers. Pessimism can be changed if you want to take a more positive outlook on life and attempt to be more upbeat. Optimism is the opposite of pessimism and it is a healthier view to have because you will look at the good side of the equation instead of focusing on the negative aspects.
