Energizer Bunny Money: Stretch Your Budget and Make Your Money Last and Last and Last

It's a conversation that most couples put off as long as they can. Most of them never get up the nerve to have it. Each person may have an imaginary version of the discussion-at many different times, in many different versions-in their head over the course of the years and the relationship. But it's devilishly difficult to find the right time, if there ever is a right time, to have the talk.

It's the love handles talk.

Most women have asked their mates, at one time or another, "Do I look fat in this?" The correct answer, of course, is always "No-you look great!" no matter what the truth actually is. The fact of the matter is that almost everyone gains weight over the years. And many people notice their partner packing on the pounds as time goes by. One or both of you may have a health club membership. More than likely neither of you is religiously using it. Perhaps you were devout about working out at first. But now, with kids, work and more, when it comes to working out, you're an agnostic at best. And neither you nor your significant other ever talks about it. You just keep on keeping on, leaving the top button of your pants undone and hanging your blouse over your waistline, or buying new outfits when you can spare a moment, which is never.

Personal finance is like personal fitness. We let ourselves go because we seem never to have the time, and it's too difficult to bring up the subject anyway. Getting in financial shape is tough. It requires focus, planning, and lots of sweat. But the end result will be a happier, more fulfilling life. Starting today, you need to make a commitment to manage your money and not let it manage you-the earlier you start, the better, although it's never too late to begin. You need to have a talk with your spouse about the love handles that your finances have been developing.

If you haven't exercised in a while, your muscles can be tight and later you may notice the muscles you haven't used in so long are a little sore. As you begin "stretching your budget," you may find this exercise is also a little painful at first as you come to terms with what you can and cannot afford. But in the long run, some discomfort in the beginning can lead to a significant financial gain down the road. Like any serious workout, constructing and maintaining a budget requires a high degree of discipline. A budget is perceived as a limiting factor rather than a plan that leads to financial success. Since many couples are not good at managing their money, they simply want to avoid the issue. Most people will say they don't have time to create and follow a budget. Some just aren't sure how to go about it.
