No point trying to compare yourself with others as everyone has different income, outgoings and priorities.
Some people are great bargain hunters and just get more for their money than others who buy without looking for sales, discount codes, cashback etc.
Some people always look for deals in the supermarket, others just buy at full price.
Some people have a new mobile phone on a contract for £40+ pm, others buy a cheaper phone outright and have a sim only contract for less than a tenner a month.
Some people have full sky package, others just have Netflix.
Some people's holidays abroad will be done on a shoestring, cheap flights, airbnb, mostly eating in and days at the beach. Many UK holidays like Center Parcs or a 'cottage in Cornwall' will actually cost more.
Some people have help from relatives, are in even more debt than you, or have received an inheritence, you really don't know.
So what you need to do is make the most of your income and reduce your essential expenses as much as you can, to leave as much money as possible left so you have some available to afford whatever it is that you think you're currently missing out on.
