Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
Assuming you are doing pretty well and are happy with your current standard of living, what would you need to maintain your standard of living in retirement? Knowing you are on track to accumulate a nest egg to support that lifestyle is a big win. Gold medals go to those who have accumulated enough assets, or passive income streams, to be in a position to retire well.
We have no non investment debt (rentals that we still mortgage), last year traveled domestically extensively (NC, TX, FL, CO, SD, NY, CA) and spent about $50K including medical, prescriptions (insulin aka expensive). I would put this closer this above Baseline at Basic income levels, all due to no debt. You can really live well for little when the debt is gone and not sacrifice. Channeling Dave Ramsey, I guess.
Even though I passed the point where my savings could cover my essential expenses quite a while ago, I’ve decided to keep working and pad my balances a bit more. Since I’ll likely have plenty of buffer by the time I actually pull the plug on work, I plan to just maintain my current portfolio, which consists primarily of low-cost, stock market index funds. Since I could always work again if necessary, I’m happy to take on a bit more risk for higher potential returns.

I personally have been working and investing through a couple of recessions – the tech boom and bust, and the recent Great Recession. Most people got nervous, went to cash, stopped contributing, etc., during these periods. The past investing decade has been really smooth. I’m not sure how everyone who achieved financial freedom will feel when we get back to more normal volatility.

The tradeoff in this scenario is clear. You can continue working to build a bigger pool of savings, which will provide additional income and flexibility for the remainder of your life. Or, you can leave your job as soon as possible and hope that a smaller portfolio will provide sufficient income. It’s all about finding the right balance given your personal situation.
