An optimist stays up until midnight to see the new year in. A pessimist stays up to make sure the old year leaves.
A pessimist is one who builds dungeons in the air.
A pessimist is a person who has had to listen to too many optimists.
An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight... the truly wise person is colorblind.
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
