Meh. This is a reflection of the same systems of toxic positivity elsewhere in the world. Yes, there's something to be said for steering the ship of your mind in a direction opposite of doom, but stifling your legitimate fear or apprehension with cliches of "think positive" sounds like it would only exacerbate it. How about instead, "it's ok to be nervous. Everyone feels nervous." Additionally, us as ethical listeners/audience members can have some grace for the real human emotions of the speaker.
