To think that we aren't just going "to the Moon," but rather traveling to meet it at an exact point in space... changes everything.
​It all comes down to orbital mechanics: arriving at the precise location, at the precise moment.
​One tiny error... and it simply doesn't happen

Charlie Munger’s 1998 Harvard speech is the ultimate cheat code for life.

He compressed 74 years of billionaire wisdom into just 30 minutes.

Most people spend 4 years in college and learn less than what’s in this video.
