First , what does optimism mean?
Optimism as quoted by the English dictionary reads, ‘hopefulness and confidence about the future of success of something’ This is a nice definition of optimism, someone who is confident and hopeful of their future.
Pessimism or pessimistic on the other hand is the evil twin of optimism, as in every aspect of life there must always be an opposite and pessimism plays this role beautifully. The definition of pessimism is an equal opposite to that of optimism, as quoted by the Oxford English Dictionary ‘a tendency to see the worst aspect of things or believe the worst will happen’ a lovely description I’m sure you will agree. Wikipedia describes pessimism or pessimistic as ‘a mental attitude in which an undesirable outcome is anticipated from a given situation’. A beautifully written explanation.
