Principles stay the same but application varies.
There’s a popular book by an American real estate billionaire.
A few years ago a friend told me he didn’t like the book because you couldn’t apply the principles to Ghana or places outside the USA..
Recently Forbes highlighted about 4 millionaires who studied the principles of that same book to build their empires in Asia and the Middle East.
Principles stay the same. Application varies.
My aforementioned friend still has a few acres of land but no buildings and no empire.
What did the other millionaires see that he didn’t?
I believe it has to do with an understanding of the application of principles.
People forget that principles will work wherever you apply them if you know how to tweak the application to your environment.
It is wisdom to hear a principle and find out how to make it yours.
