How different people are?
I have always kept account of my spending - going back over 40 years. I had �8 a week then and now well over �1,000 a week , and many �000s savings,but still follow the same rules, just use a computer now.
Use Excel to create a simple cash book listing where you spend your money each month and where comes from. Transfer some from the current account to a savings account to build up a pot of spare cash. use ISA to get tax free. Use unit trusts for longterm savings. pay off the mortage as soon as possible , never borrow money, .
just be careful, spend wisely, never on a whim. Budget each month year.
I do not live like a miser, have two nice cars and a �500K house,put 3 children thru uni with no debts.
It can be done, but always seek a better job that pays more as thet is the real way forward to a better lifestyle.
