The one question you should ask for yourself to get smarter
" If you want to get smart, the question you've got to keep asking is: Why? Why? Why? Why? "
I could totally agree with Charlie Munger here, as the question "Why?" opens the door for a new layer of understanding, like we all know that electricity is a clean renewable source of energy but why? we all know about the climate change issues, but why is it happening?
See, the question why always moves you to the next level of understanding, for the ones who are always curious to know more, to understand deeper meanings.
Stick with why, it will make you way smarter on the long run.
