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. 
After an extremely intriguing conversation with Clothier, I began to better understand the concept of arbitrage and how anyone can use it to succeed in any industry. The difficulty here is first being able to identify opportunities for arbitrage, and later being able to fully leverage those on a larger scale. But once you find what works, expanding and scaling becomes almost instinctive and native rather than some grand hurdle.
Net worth is probably the most important financial number you can track. It’s a simple way to see your financial life with a few basic calculations. Every month income comes in, and expenses go out to pay bills and rent. If after all your expenses are paid if you still have some money left over – that’s great. Now you have money to invest and grow.
Disagree with the photography idea. It may seem easy but there are those of us who have spent, in my case 10 + years learning the light, the technical aspects, the right way to pose… we have to keep pushing our prices higher because there are more people starting to eat away at the client base by undercutting…. and we’re trying to make money and feed families too. It only hurts an industry to undercut. Sorry. Good list otherwise, don’t do it as an expense to others.
22. Advertising – This is definitely the most old-school way of earning money with a blog. It’s also starting to become the least common way. You can sell advertising spots directly on your site or you can sign up with a company like Google AdSense or Media.net. Either way, you won’t see a whole lot of money from ads until your views are well into the thousands each day.
First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.
“Great list! I especially like the tutoring stuff. I’m good at Math that’s why I tutored once for my godparent’s 8th grader. I had fun with the her and her mum cooks the most delicious brownies. I don’t think I can donate a plasma or be a human guinea pig. But maybe you should add herb and vegetable planting. This job doesn’t require too many technicalities and is so far the easiest thing to do. There’s a method called square foot gardening for those who don’t have big spaces. It’s so simple to do and gardening in small boxes requires small maintenance. There is plenty of information on the web about how to do so. Once you get growing you can even sell your fresh produce to your neighbours at a cheaper price, and earn some fast money in the process . P.S. I also would want to partake in an online survey. Some people recommended Cash Crate but I’m also curious about what happened to you?
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.
