​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!
There is also an idea that we should work to build a passive income asset and then sit on the beach relaxing for the rest of our lives. The truth is that most people would get extremely bored with this scenario and will be eager to find something to do. That’s why the world’s billionaires continue to work… they love what they do and it stopped being about the money a long time ago.

I have two major dilemmas: (1) Should I wait to start investing (at least until the end of the year where I’ll hopefully have $5k+ in savings) in things like CDs? I ask because a little over $2k doesn’t seem significant enough yet to start putting my money to work (or maybe it is? that’s why I’m coming to you for your advice haha) and (2) I want to invest in things like P2P and stocks but I’m honestly a bit ignorant of how it trully works. I know the basics (high risk, returns can be volatile, returns are taxable). Do you have any advice on how I can best educate myself to start putting my savings to work?
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
