Is it embarrassing to live with your parents at 21?
I’m a 21yo guy and I still live with my parents vecause their house is absolutely amazing. It’s about 800 square meters so with 3 stories. We have our own pool and everyone has a bathroom and shower attached to their room as well as a balcony.
Embarrassing is subjective. But you shouldn't squander the opportunity you're being given. Make sure you're saving a lot of money or working towards a well paying job so you can be independent one day.
If your parents are letting you live at home consider yourself lucky and avail of the opportunity as long as you. Start putting away whatever money you are saving on food, rent, and utilities and start investing it. Go to Schwab or similar company and put your money into a broad Mutual Fund or ETF.
