True, the world is a bit unpredictable. That said, if you’re invested in a very broad index (like VTI, VTSMX/VTSAX), you are as protected as possible. If those indexes collapse/devalue, there are far greater issues going on than money. You would be fighting to eat and survive at that point, and money would be worthless. So, other than the world ending as we know it, you can be FI and have 99.9% assurance you are financially safe.

Environmental assets are not usually counted in measuring wealth, in part due to the difficulty of valuation for a non-market good. Environmental or green accounting is a method of social accounting for formulating and deriving such measures on the argument that an educated valuation is superior to a value of zero (as the implied valuation of environmental assets).[32]
Great post and right on target. I found that if you blog and/or do videos that sharing little stories will help connect you to potential leads. I do how-to videos and posts and I always tell personal stories or my own experiences that relate to the subject. It works and I get personal messages from people about it. It makes you more real and down to earth in the viewer's eyes. Once they like you and trust you they will become a lead and hopefully a sale. They may very well become a regular buyer because you will be their go to person. For best results it's best to blog daily and do at least one video a day.

Gold medals go to those who have accumulated enough assets, or passive income streams, to be in a position to retire well.
