I'm gonna guess you never read her book "How to Make Your Money Last: The Indispensable Retirement Guide"
Normally, I shudder at the thought of reading any book with the word "indispensable" in the title. However, it's on order at the library as Taylor Larimore recommends it and that's
always enough for me (the degree to which I skim the book remains to be seen, however). After a while, all these "new, definitive, latest and greatest" books on retirement investing, be it in the accumulation or decumulation phase, get old. At some point, you just create a
well thought out, well-crafted plan and stick to it.
The secret is sticking to your plan, not in changing it everytime someone says 50 is the new 40.
I did both: started a business and invested in RE. You should meet me someday. I am nothing special. It just takes the willingness to do it. I read somewhere that most men don't take too many risks, they take too few.
You have to get real about this stuff. Whether you feel you're "special enough" to invest in something of no consequence, and in fact is
extremely dangerous (overconfidence bias, among others). There's a huge difference between someone born with what is known as entrepreneurial intelligence and another who is simply "starting a business" because an author in Forbes thinks doing so will make up for stock returns
possibly being lower in the future (again: predictions = noise). Same goes for investing in real estate.
If you read venture capitalists, you will see a common thread is they make a very big distinction between investing in companies started by CEO's who are missionaries versus mercenaries. They want to invest in the Mark Zuckerbergs of the world, who are interested in building businesses because
they don't feel they were born to do anything else. These people have the persistence, doggedness, and other qualities to push through when others will quit and fail. OTOH, someone who starts a business because "starting a business is the new 60/40 PF" is an excellent example of a mercenary, with the predictability of the success and longevity of that business matched perfectly.
Investing in real estate because "investing in real estate is the new 60/40" is another fool's errand. It's been said investing in real estate is much like running a business, and if you've got what it takes, by all means go for it. As I've said, I have friends who have been highly successful in their RE investing. OTOH, here in Southern California where everybody "wants to be rich", the real estate investing graveyard is running out of room for most others.
As to taking risks in life, investing is never the place to take foolish risks. As I've posted before, success in investing is not so much getting everything right (as in guessing whether 60/40 is "dead", or
this time it really, truly, absolutely is different), but in not doing what are known as "bone-headed" things. Taking undue risk in investing is a bone-headed thing.
