Personal Finance When it comes to our finances, each of us has our own individual approach. Some of us are savers, some are spenders, and others are some-where in between. This continuum is a paradigm that our popular culture uses to frame differences in the way people approach money. I believe that the way we approach our finances goes beyond that particular behavioral characteristic. In reality, I think our approach to finances can be viewed in more of a multi-dimensional setting, where money has a different role in our lives. For some, money means survival, plain and simple. For others, money is something that is a part of their lives but rarely on their mind, regardless of the role it actually plays. For yet others, money is an obsession, as accumulation indicates achievement. Some people view money as a defensive resource to protect against future setbacks. Some people want money to provide a good home, to contribute to the ability to have certain hobbies, or to provide something to future generations and so on. Sometimes the same person may view money differently in different situations. The bottom line is that we each have our own relationship with money, and our own conscious and subconscious needs for money, rooted in our value systems. This is an area of personal finance that has interested me for a while. Why do people behave the way they do with respect to their money? What's driving this behavior? Of course, a starting point for anybody is to consider how you personally view things. Taking an introspective approach，I have spent time figuring out my own take on money，and the role it plays in my life. What I have determined is that for me，it fits into a framework that includes the following elements：health, wealth, and relationships. These are linked together as a part of a system. They're all connected, and to the extent one is strengthened, the others will be strengthened as well. If one is weakened, the others will be weakened as well. So to me, money is a part of the wealth aspect of HWR. Beyond basic survival, money gives you the opportunity to live a healthier life, with the time and means to have more positive relationships. One thing I want to make clear is that I am not saying that money buys friends. Well, it could, but those aren't true friends. What I am saying is that the more money you have ,on balance, the less stressed you are about it, and the more time you have to do other things, such as cultivate true, genuine relationships that aren’t based on money. Money is but a component in the system. The approaches to finances vary from person to person.（） Money plays the same role in our lives.（） Some people think of money as a means of donation. （） Although money is part of their life, some people don’t attach more importance to it.（ ） Some people use money to cultivate their hobbies.（） People’s attitudes towards money may change in different situations.（ ） The writer is an export on money management.（ ） According to the author, money is the most important in HWR.（ ） With money we can buy anything including true friends.（ ） Money is only a part of the HWR system.（ ）
