optimistic
In most cases, "optimistic" describes a positive mindset. It is commonly used with the preposition "about" (e.g., optimistic about the future) or followed by a "that" clause. Be aware that in professional or financial contexts, calling a plan "too optimistic" can be a polite way of saying it is unrealistic or unlikely to happen.

🎬Tuesday afternoon, Chloe is in the library staring at a failing grade on her laptop.
David Smith
Just checked your portal. You're still optimistic about passing this class?
Chloe Smith
I'm literally spiraling, dad. My GPA is in the gutter.

David uses 'optimistic' to question if Chloe still believes a positive outcome is possible given her grades. Chloe responds with 'spiraling' (slang for losing emotional control) and the idiom 'in the gutter' to describe her plummeting grades, highlighting the contrast between David's corporate-style inquiry and her dramatic student persona.
