One can never be prepared enough to be Alexander the Great, one can never be prepared enough to be the President. Similarly and realistically, you can never be prepared enough for the new, the bigger, the greater, and lots of times the unimaginable.
What is in the word ‘Preparation’?
Preparation is the art of building your stairs, gaining altitude (or flying for the first time, in case your preparation means a balloon). Preparation is to equip yourself firstly spiritually, secondly mentally and lastly technically.
Planning takes time, thinking takes time. The pursuit of happiness is meant to be a selfish design process that might take years, decades, solitude, blood and tears to produce a lot of false prototypes. However, the pressure and pain are truly worthwhile, for the sake of a majestic and elegant diamond you are meant to become.
It is true you can never be prepared enough to be. But once your preparation gets you to the place where you thought you desired, you should be prepared to execute bloodily with grace, like the Romans.
