You may well be spoiled, but I think context is everything.
My grandparents never owned a home, went to college, or traveled outside of the US.
They said my parents were spoiled who managed to buy a condo in their late 40s, took some classes at a community college, and went to Aruba twice.
They said I was spoiled because I bought a house at 25, earned two degrees, and have been to multiple countries.
My daughter meanwhile is 18, plans to start saving for a house this year, and got into a really difficult nursing program, with a massive academic scholarship, and has traveled since she was one. Is she spoiled?
Personally, I reject that label in all of these cases because whatever each person achieved, whatever benefits they had, stuff they owned, or places they went were the result of their own hard work and that of those who came before them. There were no handouts. Everybody made their own money and paid their own bills. Some as adults, some a little earlier.
The point is, if you’re a kid, the best way you can avoid being spoiled is to truly appreciate what you have, understand that many people are not so lucky, and know that whatever benefits you’ve inherited from your parents are privileges that should not be taken for granted. Then, start taking ownership of things in your life (do your own clothes, clean your room, shovel when it snows, etc.), get a job or volunteer when you’re old enough, and bust your ass in school to be the best student you can be.
Expect nothing but be genuinely appreciative when gifted anything.
Good luck!
