At this time of year, you might be tempted to draw up a long, overwhelming list of goals for the coming months. Fortunately, there's an easier way to put your best financial foot forward: If you can avoid a few common money missteps, you'll be on your way to a richer 2014 and beyond.

The Incredible Shrinking Paycheck

You'd like to save more for retirement, increase your emergency savings and pay off your credit card debt. But no matter how much you want to do the right thing, you find yourself spending your cash as soon as you earn it. Here's an easy fix: Automate as many financial decisions as possible. Have the bank transfer a set amount every month from your checking account to your Roth IRA and savings accounts, and set up auto-pay for your credit cards. (Be sure to submit at least 10 percent more than the minimum due to pay off the principal sooner and limit interest charges.) The less you have to think about how to spend every dollar, the more likely you are to spend wisely.

The Stagnant Stash

Cash—in savings accounts, short-term CDs or money market deposits—is great for an emergency fund. But to fulfill a long-term investment goal like funding your retirement, consider buying stocks. The more distant your financial target, the longer inflation will gnaw at the purchasing power of your money. What you can get for $100 today will cost nearly $200 in 20 years if inflation averages 3.5 percent. Long-term investments that currently sit in cash accounts are likely earning less than 1 percent interest—that's not nearly enough to beat the inflation rate.

The Never-Ending Car Lease

Consumer auto research firm estimates that Americans brought home 15.6 million new cars in 2013, the most since 2008. What worries me is that one in four of those cars was leased. If the lessees are rolling into a new contract every three years—as many are—they're going to be making monthly payments indefinitely. If you're shopping for new wheels in 2014, don't lease. And when you buy, get a 36-month loan, even if the dealer offers 60 months. Your car is a depreciating asset. Borrow the smallest amount of money possible and pay it back as soon as you can.
