Donating plasma can actually work out better than selling your blood.  It takes longer to donate plasma because they will put your red blood cells back in your system. The upside is that you can donate plasma as much as twice a week and you can make anywhere from $40-$60 per donation. You can make that $100 in less than a week if you can stomach the needle.
Selling clothes you no longer wear is a quick way to make some money. Start with local consignment shops for faster cash, or use sites like ThredUp and Poshmark to find buyers.

What It Is: Transcription essentially involves you listening to audio files and typing out what you hear. Easy enough, right? Companies usually hire transcriptionists without much experience, so some job postings might only require you to have a computer and keyboard to get started. Transcription jobs can vary from transcribing a college lecture to a doctor's medical dictation, while most companies allow you to make your own schedule.

Most of them have told me that if I’m interested in consulting, I have to talk to someone at Deloitte. Do you think I could pick your brain on your job and what motivated you to choose Deloitte? I’d especially love to know how you made your choices after graduating from Michigan State. [THE PHRASE “PICK YOUR BRAIN” IS ONE OF THE BEST WAYS TO ASK FOR ADVICE AND FLATTER, AND “MICHIGAN STATE” REINFORCES SHARED BOND.]

Harris, I think it depends on several factors. First, I recommend having a well established emergency fund that will be enough to cover several months living expenses. This will help you cover any unexpected expenses and avoid taking out additional debt. Next consider other short/medium term goals. For example, are you saving to buy a house, do you need to replace your car in the next two or three years, etc. Finally, consider the interest rates of your student loans and what you may be able to earn in an IRA and decide which option is best for your needs. Investing for retirement now could be a huge benefit for you and your wife when you reach retirement age, but eliminating debt increases cash flow and gives you peace of mind. Both options are solid. Best of luck.
Another advantage of having some cash savings is the ability to use the money for investments or other large purchases when you come across a good deal. This could be a something like an investment, property, or just a good deal that saves you thousands of dollars on a major purchase. Take advantage of these principles and save money whenever possible.
