My Investor formula. How did I get her out and why? I think Smart-Lab will appreciate it.

Greetings colleagues!
I decided to write a post about my Investor formula that I strive for. At first sightit looks very simple, but it is very difficult to come to such a point that you can live on % of your capital!
So, here is the formula itself:

What's so interesting about it?
All income that an investor receives from a salary or business is directed into capital!
In the capital itself, we reinvest 80%, and we take 20% for our expenses!
Every year the capital will become more and more powerful, because we are constantly replenishing it and the capital itself is constantly reinvesting!
It should be noted that the capital should preferably contain conservative investments and preferably in different currencies (so that the capital is protected from differences in exchange rates).
I recorded a video on this topic, I think it will be interesting for beginners to watch it.

What can you say based on this formula? and which one do you live by? It will be very interesting to read your opinion. Thank you for your attention! See you in the next post.
