Today, I am optimistic. I am full of optimism, full of...
...an outlook on life such that one maintains a view of the world as a positive place, or one's personal situation as a positive one. It is the philosophical opposite of pessimism. Optimists generally believe that people and events are inherently good, so that most situations work out in the end for the best.
Alternatively, some optimists believe that regardless of the external world or situation, one should choose to feel good about it and make the most of it. This kind of optimism doesn't say anything about the quality of the external world; it's an internal optimism about one's own feelings.
