Several times recently I've seen posts from people who 'can't save on a high income'.
Is saving up a lost habit? I'm sure back in my parents and grandparents generations saving was just something that everyone did.
Don't buy what you can't afford and save up to spend later.
I'm the sole earner on an average salary (mid £20k's) and I save as if it was any other bill. It goes out on payday along with the mortgage, gas and council tax.
