I have one credit card. I use it to buy groceries, gasoline, pay bills and what not.
At the end of the month, I get a statement, I pay off the balance and life goes on.
Of course, I'm lucky in some ways, I don't live in an area of the country that has a high cost of living (if you don't count taxes), I have a decent job and I'm not one to live it up. I've had a job of one sort or another since the age of 12, except for brief periods when I went away to school.
My idea of a vacation is to hang out at home, go on a day trip to someplace nearby, veg out at home and read a book. My parents are the same as I am, they're big savers too. So I guess I've learned it from them. I drive a used car, which I've owned since 1998, pack my own lunches, wear clothes until they're threadbare, I put as much into my 401(k) plan as I can get away with.
Yes, I'll admit, I'm the biggest bore, definitely not the stuff that a mini series is made of. But I do have something going for me.
Whenever there is a sudden need for money, I have it. Whenever my son needs money for books, if I have to get something fixed around the house, when bill time comes, I'm all set.
There is such a thing as living below your means. Once you realize that you don't need the biggest, the latest, the best, you suddenly feel more wealthy. Contentment is a means of achieving wealth. And wealth is not always material, it sometimes manifests itself as understanding and wisdom. Be a good steward of the money that comes your way. Realize that money is a good servant but a bad master.
When it comes to investing and savings, I think of the fable of the tortoise and the hare. Slow and steady wins the race. Invest and save a part of your paycheck each week, pay yourself first. In time you'll be amazed at how much you have.
Another fable that is instructive is the grasshopper and the ant. If you plan for the future and sacrifice today so that you'll have what you need tomorrow, you'll very likely do well. On the other hand, if you want to live for today... well, there's always tomorrow, but tomorrow may not be very pleasant!
