Everyone should learn how to code, it teaches you how to think.
You don't have to be a Genius to know how to code you just need to be determined.
The computer is incredibly fast, accurate, and stupid; man is unbelievably slow, inaccurate, and brilliant; together they are powerful beyond imagination.
