First: I understand why you would say that such investments are restricted to only accredited investors, because generally, that’s true. There are means, under federal securities regulations and Blue Sky laws in each state, to sell interests to non-accredited investors – but usually those means are so heavily regulated and involve disclosures so similar to cumbersome registration requirements that it is not worth it for the seller to offer to non-accredited investors.
I get excited every paycheck because I know my investments are going to increase by a decent chunk. I use Mint to keep a close eye on what the current value is at and make goal marks to hit. Every time I hit a goal, I do a little happy dance and decide what I want my next marker to be and when I want to hit it by. I’m nowhere close to being financially independent or even debt free, but it’s exciting to see the ground work being laid and watching it grow.
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.
