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.
One great way to generate a passive income is through affiliate marketing. Now, this does depend on the size of your list. Yes, size matters when it comes to your list. Especially if you're looking to make some serious money and do it on autopilot. But, list-building takes time. It doesn't happen overnight. And you need to add value to your list or you become obsolete.
EQ Bank Savings Plus Account 2.45%*-This is one of the highest rates in Canada.  There are no fees, no minimum balance, you get UNLIMITED FREE INTERAC e-TRANSFERS® (my usual bank charges me over $2 each e-transfer!).  There is no physical branch, it is all done online.  It is a trademark of Equitable Bank, which is a Canadian bank that has over $23 billion assets under management.  The maximum balance is $200,000, which is a good problem to have if you have more than that to plunk in a savings account 😉 (they recently increased it from $100,000).  Rates are of course subject to change without notice, so better act fast.  Here’s my review of EQ Bank, I recently signed up.
The United States Internal Revenue Service categorizes income as active income, passive income, or portfolio income.[1] It defines passive income as only coming from two sources, or "passive activities": rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
