A Possimistic Person View: OMG it's going to be so cool tomorrow when we leave its gonna be the bestest day no matter what happens or anybody says..............
An increasingly relevant wordplay on the cliché "cautiously optimistic". As the world continues in free fall, its much more realistic to expect negative outcomes. Therefore, its much more pragmatic to maintain a cautiously pessimistic demeanor, rather than a cautiously optimistic one.
My cat is always cautiously pessimistic when inspecting anything new that I bring into the house.
A posimistic person is someone who has a very positive, affirmative, optimistic, favorable outlook on life.
It's actually a combination of the words postive and optimistic, hence " posimistic", "posimist " & " posimism ".
The opposite would of-course be "negamistic" , "negamist ", " negamism ", which is a combination of the words " negative " and " pessimistic " !
"Charlie is always posimistic, expecting the best in this best of all possible worlds, but sooner rather than later he must come to the realization that he cannot have his cake and eat it too !"
