I have NEVER had a credit card in my life.
I do not propose to get one any time soon.
I have never been in debt except when I had a mortgage.
Paid the mortgage off 26 years ago.
Always pay in cash including all utility bills, through the Post Office.
With cash only I have always forced myself to budget on a weekly basis. Must have saved thousands of dollars over a lifetime, by so doing.
If I run out of cash, I can't buy anything. THAT forces me to budget carefully.
I now eat very well, I am well clothed, I live in my own house, I have a high performance Mecedes car (bought with cash), and a coin collection worth many $thousands.
All achieved by working with integrity and honesty.
