This is one of the main causes of stress for many people. No matter how much you make, it doesn't seem to be enough. If you are going to conquer your stress about money, you will need to sit down and get a clear picture of your financial situation.
How much of the money you make are you spending on things that you want, but don't really need? Get a handle on unnecessary expenditures if you want to lower your stress levels.
Figure out how much money you have coming in and where it is going. Then make a realistic spending plan for getting your finances on track. Once you have a plan in place that includes paying down debt and saving a portion of your pay for emergencies and retirement, your stress levels about finances will go down.
