Have you manifested something big?? Is this even real?

Why everyone is posting success stories like manifested a car parking, a chocolate, a free drink, white feather, etc. Have you started manifestation for these trivial things? You guys have got these things without even manifesting. Is there anyone in this sub who has actually achieved something concrete, big or impossible things in their life with manifestation??? Or everybody is happy with getting a car parking or a free drink. Anyone manifested anything with RA as I am doing RA from last 2 months with a single affirmation but didn't see even a small movement. Sometimes it feels like just a waste of time.
