Grateful.
Gratitude and complaining cannot coexist. Attempts to have it both ways emerges when we include a “but” in the sentence. I’m so grateful for __________, but I hate it when __________________. What? How can a feeling of generosity and an attitude of stinginess exist in the same thought? The latter discounts the former.
So choose which attitude you value most and stick to it. You can’t have it both ways and be happy.
