I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.

If you have a knack for teaching and if you are an expert in some subject, you can become a tutor online for students. There are tons of websites like TutorVista or Tutor.com where you can try out this. You would need a great internet connectivity for this. It can work best for someone who is ready to work late in nights as many students from US and Canada would be right fit for you then.
In addition to opening a brokerage account, you can also invest in peer-to-peer lending firms like Lending Club. I’ve been using Lending Club for a few years, and my net annualized return was 6.02% percent last year. Picking the right investments is easy since the platform offers automatic investing, but you can also pick your own notes if you're brave and want to learn the best ways to leverage the Lending Club platform.
I really enjoyed how you listed all of the reasons to build passive income streams as well as the framework. You also made an interesting point about freelance writing on how the more skilled writers want to keep posts for their own website. Good insight because freelance writing is something I’ve been looking into for income recently. Also, it’s amazing what you’ve been able to accomplish with your blog over the past 6 years. It’s so motivational to see the success of Financial Samurai. I’m not in a place to afford any consulting, but, I wish I could pick your brain or get mentored by a successful blogger such as yourself…Not trying to blow smoke lol. It would just be so great to have someone who’s done it provide guidance around the direction of the blog, ways to earn, and on the general concept. Always enjoy your posts. Thanks for sharing :)

These days, low-risk bond yields aren’t enough to meet most income needs. When investing in bonds, the income typically comes as coupon payments – contractually guaranteed interest payments at predictable intervals.  There are many kinds of bond income available, so you must strike a balance between reaching for higher income (yield) and limiting risk.
