Test websites. Remote usability testing means getting paid to navigate a website for the first time and giving feedback to the website owner. Most tests take approximately 15 minutes, and you can get paid up to $10 for each test. A test involves performing a scenario on the client’s website and recording yourself doing it. For example, you might be asked to go through the process of selecting and purchasing an item on a retailer’s website.[1]

I wasn’t thinking so much of plagiarism as I was about the simple act of someone sharing and passing it along to someone else. With e-Books, for instance, although I know there are several formats for them, I assume they are mostly PDFs to download. I don’t think it’s possible to password protect a PDF for opening (I think you can do it for printing or editing), nor to have some kind of time limit on being able to open it. As for courses, how do you ensure that the link or file doesn’t get passed around and accessed for free by people who didn’t pay?

Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
As far as transportation is concerned, it has been included in the ‘Rent and Utilities’ and ‘Travel’ categories. The ‘Rent and Utilities’ is a bit high, so that we can live in central locations and not have to rely on paid transportation too much. The ‘Travel’ category covers our flights between Scotland, America, and whichever other country we decide to live in but it also covers things like taxis and buses (I’m accumulating millions of frequent flyer miles between now and when I reach FI so that our airfare costs will be extremely low…more on this in future articles).
In the western tradition, the concepts of owning land and accumulating wealth in the form of land were engendered in the rise of the first state, for a primary service and power of government was, and is to this day, the awarding and adjudication of land use rights.[citation needed] Many older ideas have resurfaced in the modern notions of ecological stewardship, bioregionalism, natural capital, and ecological economics.

If you have 20 years left to live and only require $60,000 a year, having $1,200,000 can also be considered enough even if you make zero return. The only problem is that your purchasing power will decline by ~2% a year due to inflation. The other problem is that you don’t know exactly how many years you have left to live. Therefore, it’s always better to have more rather than less.
