The human mind is a great and mysterious tool.
And like any tool, it needs forming and sharpening.
If you want to expand your mind beyond your imagination, I recommend reading The Fountainhead and Atlas Shrugged by Ayn Rand.
Those two books will help you expand your mind and your perception of the world to a new level, no matter the level you are starting from.
The Fountainhead and Atlas Shrugged.
With love, yours truly, Cristian.
