Optimism is the habit of expecting good things to happen or believing that problems can be solved.
From Latin “optimus” meaning “best,” through French “optimisme.” It originally referred to a philosophical belief that this world is the best possible one, then softened into a general positive outlook.
The word started as a serious philosophy claim that this is literally the best world that could exist—not just a mood. Everyday optimism is like a tiny echo of that huge idea: acting as if better outcomes are realistically possible.
