Moral Of The Story (Mental Note To Self)

It’s different strokes for different folks because the world don’t move to the beat of just one drum, and what might be right for you, may not be right for some, so in regards to yours truly, it is essential for me to know the difference between what is and is not essential according to my own perception, and it is nonessential for me to explain why knowing the difference between the two in regards to investing is such an important matter with what is currently unfolding in society as of current press time.
