Delaying that ultimate goal in order to work more than the hours necessary for your general support may be counterproductive. Of course, that is a matter of personal choice and philosophy. This is meant to be a rough guideline. Try to be realistic in assessing your own limitations. Another suggestion is that you try to obtain employment in an area related to your major.
Some colleges even offer college credit for such employment.
See a counselor for information about this. In addition, in a competitive job market, a new graduate who has experience in a field may have an advantage over applicants without experience. Let me offer one additional suggestion on financial aid. Many people do not apply for financial aid because of misconceptions about how it is appropriated. Financial aid is not based on ethnicity or race and you do not have to be impoverished to receive it.
