Apprenticeship
The principle is simple and must be engraved deeply in your mind: the goal of an apprenticeship is not money, a good position, a title, or a diploma, but rather the transformation of your mind and character — the first transformation on the way to mastery.
You enter a career as an outsider. You are naive and full of misconceptions about this new world. Your head is full of dreams and fantasies about the future. Your knowledge of the world is subjective, based on emotions, insecurities, and limited experience.
Slowly, you will ground yourself in reality, in the objective world represented by the knowledge and skills that make people successful in it. You will learn how to work with others and handle criticism. In the process you will transform yourself from someone who is impatient and scattered into someone who is disciplined and focused, with a mind that can handle complexity.
