This is a bit deep so please be kind!
I grew up in a council house in the 80s/90s with the housewife Mum and manual low paid worker Dad, all good. In secondary school, I went to a school at the other side of town where most parents owned their house. As I got to 14/15 I began to feel inferior and poor, my school trousers had holes in the crotch whilst my friends wore Tammy Girl. I went on to have a child at 18 and threw myself into being a Mum and fighting the stereotype of a teen Mum, would go to many baby groups. Because of my age, I again felt inferior and I was a size 20 so lacked confidence. I later went to Uni and have a fantastic career and have lost weight and feel good. Still don't own my home but live in a lovely area, we may buy but mortgage rates and economic instability have put us off - rent is cheap and we dont have to worry about unexpected repairs.
I currently drive an Audi, and previously a Merc. I'm looking at my next car and want to step up in prestige so for a long time have said it would be a Porsche family car.
I heard someone say the other day on TV "stop spending money on things you don't need to impress people you don't like" and it has made me question my motives!
TLDR: My career and car make me feel like I can hold my head up high. Things that need me feel inferior: growing up in a council house at school with mostly fanilies who owned their homes, being a teen Mum, being obese. I am very proud of my career and now want a Porsche to replace my Audi. I have always felt that people have looked down on me/had an inferiority complex and things like this grow my confidence.
YABU: you probably don't really want a Porsche, you are just trying to impress people
YANBU: A Porsche is a sign of doing well and will make you feel good to reach a new goal
