If you are a freelance writer you should try to find freelance work that guarantees income on a regular basis, so that you have a regular source of income.
You should try to write a number of articles per day, per week, or per month for this market.
This is especially true if most of your income or all of your income comes from freelance work and freelance work assignments.
After you decide on this guaranteed market, whether it's an online market and/or a print market, such as a local magazine, then you can do the freelance assignments on commission or bid for assignments at Elance, Freelance Work Exchange, and/or advertise at forums and/or classified ads websites.
This income is not guaranteed and not necessarily on a regular basis. However, if possible you should try to obtain a client who needs regular writing assignments, for example, a company who commissions writing on a regular basis, such as how to booklets, advertising, or employee brochures.
Freelance writers can often discuss their "cash flow" problems just like other business people. However, by having these guaranteed income jobs, even if the pay is very little, and/or the few clients who assign works on a regular basis, even though this is not a regular salaried employment, it does help your "cash flow" problems.
You should also put together a budget based upon how much your can afford for various items.
In addition, you should have a tax fund in case there is money to be paid in taxes, a percentage of your monies earned goes into this tax fund.
Other funds might include investments, savings account, etc.
