There is that point of view.
I was married by 20, with a baby on the way.
By 32 I've got two houses ( i have one on buy to let) and all ive ever done is drive a van.
I've always got the DFS sofa on buy now pay latter, and done the same with electricals, I've just bought a new TV today on buy now, pay later.
If you pay it by the due date, it makes no odds. If you have the money people say, why not pay for it now?
Because i dont want to, thats why.
My old man was the same, he made his money, had money in the bank and he still bought now and paid later on things.
You need to know your limitations and dont over spend, credit cards and interest free credit are handy things if you have more than half a brain, but also the worse things to get involved with if you dont.
