Tutor students. If you have an academic specialty and can squeeze in a couple of hours during the week while Junior is taking a nap or Janie is at gymnastics, share your knowledge with struggling students. Find students looking to improve their grades on your own through your kids' schools – check a site such as Craigslist.org to gauge hourly rates in your area – or sign on with an online tutoring company, such as Tutor.com. You must be available to tutor at least five hours a week and have a college degree to tutor certain subjects for Tutor.com. Tutoring is done virtually from home via a computer, not in person. Tutor.com tutors are paid an hourly rate based on the subject.

Not only will this multiply the money you’re bringing in in a serious way, but it protects you against any sudden changes in the market or in your business. Remember that old saying about putting all your eggs in one basket? A few hours a week committed to just one or two of the following opportunities will put you in a much stronger position to be financially safe and independent.

What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
