I'm 27, so I'm considered a 'millennial' and I work full time, volunteer with the homeless, have two little dogs. I currently rent with my other half whilst we save for a house of our own. The rental we have is much bigger than a house we could afford to buy, so we'll stay put for a few more years. Yes, we're going to Paris for a few days at the start of next month but why shouldn't we? We both work full time and have done for many, many, many years. And, travel now-a-days is a lot cheaper than it used to be, 4 days in Paris, with flights and accommodation costs £400, for both of us.
My car is on finance because the cost of repairing my old car was beginning to get a bit silly so it made financial sense to do so - instead of taking away the savings of my deposit for a house in order to get a car. I need a car to get to work, its not a luxury, its a necessity - and its a Ford KA, not a luxury car at all!
It is harder now to get on the property ladder than it was a few decades ago, only about 20% of my friends have bought houses. The rest are living at home and saving, or if circumstances don't allow (my mother is dead) then they're renting, like me, as where else would I go?!
We work hard, we save and we spend. If we didn't 'spend' then there would no doubt be problems with that as the economy would suffer. It's all about finding a balance, enjoying life, working hard and saving.
I'm by no means in a quarter life crisis.
