Sorry I didn't like your argumentation style. Your first two points (gratitude and cynicism) are mostly strawmaning tbh, and don't really construct anything for your conclusion?

If your main point is that we ought to act ourselves to create a world we like, I wholeheartedly agree with you. But maybe I misunderstood.

Anyway strawmaning is bad, especially that your arguments stand buy themselves, and to me cut into the overall credibility.
