The question is grateful to who? You would think grateful to Allah, but Allah didn’t mention Himself. So it could be grateful to Allah, grateful to your parents, grateful to your teachers, grateful for your health, grateful to friends. Grateful to anyone who’s done anything for you. Grateful to your employer for giving you a job. Appreciative. Grateful is not just an act of saying Alhamdulilah. Grateful is an attitude, it’s a lifestyle, it’s a way of thinking. You’re constantly grateful.
