Language that speaks of hopes, dreams, and affirmations (“You are the best!”), this kind of language--let’s call it high motivation--has its role. High motivation is not the kind of language that ignites people. What works is.. speaking to the ground-level effort, affirming the struggle. Phrases like, “Wow, you really tried hard,” or “Good job, dude,” motivate far better than empty praise.
