Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer without having a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
Great message, Jeff. When I look at big goals, or even incremental goals, I like to break them down into bite size bits. Earning $100,000 a year seems difficult in many situations, but it seems easier when you break it down to $8,350 a month, or roughly $280 a day. Sure, that is aggressive for many salaries, but there are many ways to fill the gaps with side income, owning a small business, consulting, freelance work, etc. The same concept works for any number or goal you want to reach. Find out where you are, and what it will take to reach the next step. It’s much more attainable when you make incremental goals.
It sounds a bit like a cliche, doesn't it? Just add value, and everything will be better. But how many people do you really think go out there into the world with the desire to add massive amounts of value? Clearly, many people are out there to do the least amount of work for the greatest return. That mindset is born from the id. It's instinctive, and hidden within the far reaches of our subconscious mind. Overcoming that is a hurdle, but a very necessary one to make.
Jeff have you ever considered adding something on price comparison sites for selling your used stuff? One of the fastest 100 bucks I have made so far was just from old textbooks and dvds on price comparison sites that give you the best offers. I know Bonavendi.com is a good but im sure there are others. Anyway would be interesting to see your take on the matter, the other ideas I found really creative though. Thanks for the read brother
Some of the “gotcha” job offers from the past include check-cashing schemes, mystery shopping, medical billing “jobs” that require you to purchase expensive computer software, and craft-making jobs that ask you to pony up the cash for materials before you get started. And let’s not forget about the famous envelope-stuffing scam that was nothing more than a pyramid scheme designed to siphon money from as many people as possible.
Online teaching jobs can be found at a number of different websites across the web. If you’re interested in TEFL jobs, VIPKID, Gogokid, EF Education First, and Hawo American Academy are legit sites to look for jobs. For general tutoring, websites like Tutor.com and Varsity Tutors are good places to start. Keep in mind that you’ll likely need to complete a video interview before being hired.
Offer to watch children or pets. If you know anyone who has children or pets, you could easily begin a side gig as a babysitter or pet sitter. To let people know you’re interested, send out a group email describing your services, post an ad on Facebook, or tell friends and acquaintances about your availability in person or over the phone. You can also create a profile on a babysitting referral site like Care.com.
You can either organize a yard sale yourself (which is kind of a hassle), or better sell the items through ThredUp, which will pay somewhere around $2-$25 for staff from Gap, Banana Republic, H&M, etc. You can browse around to see how much different items are worth. The best thing about ThredUp is that all you need to do is pack your clothes in a box and then just ship it to them (shipping costs are covered by the company).
You may not realize it, but online writing jobs can be found in a bazillion different places. Think about it, every website needs somebody to write content.

Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
