This is why we can retire in our 40s. we currently have four streams of income (my salary, husband salary, husband pension and our passive portfolio income which is outside of all our employer retirement accounts). our passive portfolio income is surpassed what most people are aiming for their retirement portfolios. And we don’t sell anything…this is just our dividend income annually. Passive income is the key to flexibility. No employer necessary.
Given the growth in the sharing economy, your junk can start to pay for itself. For example, if you have some awesome vintage furniture inherited from your grandmother sitting in a storage unit, you can rent this out to photographers for their “styled shoots” which are becoming all the rage. If your furniture is more modern but you still can’t bear to get rid of it – perhaps a home stager will be interested.
It’s a (mostly) short term, higher risk, higher reward place to invest cash that has a low correlation with the stock market, but is far more passive than buying and managing properties, has more opportunity for diversification than private placements (minimums of 5-10K, rather than 100K), and most of the equity offerings (and all of the debt offerings) provide monthly or quarterly incomes. Unlike a REIT, you can choose exactly which projects you wish to invest in.
An item of deduction from a passive activity that’s disallowed for a tax year under the basis or at-risk limitations isn’t a passive activity deduction for the tax year. The following sections provide rules for figuring the extent to which items of deduction from a passive activity are disallowed for a tax year under the basis or at-risk limitations.
Creating original content that other people love can be very rewarding to you from a personal growth perspective (people value something you have created) and from a financial perspective (people are willing to pay you for it).  You create something once, but keep getting paid a royalty for it long after you completed it.  Music is a nice example.  You write/perform the song once, and then sell it online.  Each time someone downloads your song you are paid a percentage of that sale, what a nice way to generate passive income!
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.
