You're not David Beckham. You just didn't sign a five-year deal to play soccer stateside for a whopping $250 million. Your wife isn't out in Los Angeles trying to find your new multimillion-dollar home.

So what's the deal, friend? Why are you spending your greenbacks like you've got money to burn? Why are you maxing out your credit cards, looking at houses you can't afford, and driving a car where even making the insurance payments is a challenge?

I'm not coming down on just you. Living beyond our means is a national pandemic. We all want to live a posh life even if we're not married to Posh Spice.

I've got a plan, though. Let's see if these simple tips can help you look good even if Pepsi, Adidas, and Gillette don't come knocking on your door for endorsement deals.

1. Don't go offsides
There are fewer concepts easier to grasp than living beneath your means. Even raking in $50 million a year still has limitations as to the size of private jet, yacht, and island that you can feasibly acquire. It's not all that different when you're making just $50,000 a year.

If you have more money going out than you have coming in when it comes to after-tax income, you're offsides.

It's a common problem. Payday loan companies like First Cash (NASDAQ:FCFS), Cash America (NYSE:CSH), and EZCORP (NASDAQ:EZPW) are making a mint in charging exorbitant interest rates on short-term loans. These companies prey on consumers who can't even live paycheck to paycheck, so they borrow against future paychecks.

It's no surprise that many of these companies also operate pawnshops. Once you find yourself in that kind of downward spiral, it's often a matter of time before you're hocking your heirlooms.

The solution is simple, non-Beckham. Implementation is the real bugger. It takes a great deal of humility to admit that you should be moving into smaller digs, trading in your pricey car, and eyeing the dollar menu for sustenance. Yes, Beckham is the one with his own brand of aftershave, but you're the one who needs to shave down your scruffy expenses.

You can do it. If you're married, your spouse needs to buy in, too. Know where you stand, all the time. Never go offsides again.

2. Score some goals
Cutting back doesn't mean euthanizing your dreams. You can still think big, only now you'll have a realistic plan to get yourself there. That's where budgeting comes in.

In the first step, you simply went on a top-heavy trimming tirade to get yourself under the nut. Now it's time to understand where your money is going.

3. Celebrate in style
Perhaps the hardest part of living below your means is the realization that your means may ultimately begin diminishing. Despite his gargantuan deal, even the biggest Beckham fan has to agree that his skills are in decline. This will probably be the most money that he ever makes on the soccer field.

But don't worry about Beckham. The money tree won't dry up for him. His charismatic ways will keep him in the spotlight, albeit a dimmer, lower-paying spotlight. So even he has to enjoy the moment but also keep an eye on the post-game festivities.

You and I aren't all that different. Our skills will diminish in time. The time to plan for our eventual retirement is at our peak, not when we wax nostalgic over the missed opportunities to prepare for the inevitable.

Do you want to write books like General Electric's (NYSE:GE) Jack Welch as you coast through your golden years? Would you rather cruise into that retirement -- literally -- as a perpetual customer of companies like Carnival (NYSE:CCL) and Royal Caribbean (NYSE:RCL)?

You have the power to decide. Just realize that the grander the plan, the more you'll have to save for before you hang up your cleats.

Save it like Beckham? Now that's a good game plan.
