Can you get direct deposit for your paycheck? Just wondered. Perhaps, if you didn't have the cash in hand, you wouldn't be as tempted to spend it?
Also, if you're worried about saving, can you have some investments, in small amounts, deducted from your pay? I have Savings Bonds (yeah, I know, you don't get rich on them, but they don't require a large output to buy when using payroll deduction. They are tax-free until you cash them in, and actually usually get a better interest rate than what's out there now in CDS, for example. They are totally backed by the govt, and are very safe. I get $50 taken out each pay--you can do as little as $5.) I also have my IRA deducted, and extra pension, and a slush fund savings account--which I had to open to get the IRA. I aslo have deferred compensation (mutual funds) deducted. This is very hard to touch until retirement, but mine has done quite well over the past 10 years. I now have $37,000 in it that I never missed out of my pay! Also, when I get my annual raise, I always take that amount, and increase my amounts of one of the above funds.
If you can't do any of the above: start by cleaning out your purse every week, putting any change (and try to throw a bill or 2 in) in a jar. It's simply amazing how much this adds up. I've been known to break a bill, in order to generate change for my jar! (OMG, am I CHEAP.) Or, even use the jar method just for "fun" money, and save your regular pay for bills, etc. Get into the spirit of the thing--make it fun to see how much change you can save up--or maybe, I'm just a pathetic person, who needs a life!
Another trick: you can buy Savings Bonds online. When I used to get an urge to go online, and buy something I really didn't need (I LOVE eBay), I'd go to the Treasury's website, and use my credit card to buy...you guessed it! Craving satistifed; no waste of money; and, by "buying" something, I actually "saved" money!
When I was single, living with Mom, I used to make savings a game, by challenging myself to save as much as I could. It's the only thing I miss about being single--I used to sock away most of my pay for retirement!
Another trick: when a long-term loan payment is done, I take that payment amount, and invest it. I did this with my 5 yr car loan, paying it off in 2.5 yrs. I figured, if I never missed that money then, why not keep "spending" it by saving it? I still don't miss that $223.75, and that was over 7 years ago. In fact, it spurred me on to challenge myself to save even more.
Take heart--you can "cure" your spending problem. Until DH met me, he was a big spender. He had $40,000 worth of debt (on "toys") when he met me June, 2003. We got engaged in 9/03. By 12/03, he had gotten his debt down to $26,000--all of this with a life-change event (moving in together in an apartment that was almost twice his previous rent; and getting a new job). We'd be in the grocery store, he'd throw an impulse purchase into the cart. I used to shoot him a look; he quickly learned. He'd say, "I really should put that back, I don't need it."
(My kinda guy!). I got him to learn to save, and to finally save for his retirement. I told him, "Honey, you're going to graduate summa cum laude from the MargeCat School of Economics!" He still has a bit of debt (he got a debt-consolidation loan shortly after we bought the house. Those 29% credit cards were KILLING him., but he's really turned his way of thinking around.
