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.
Practical knowledge is the ultimate commodity, and is what will pay you dividends for decades to come—far more than the paltry increase in pay you might receive at some seemingly lucrative position that offers fewer learning opportunities.
Working at these skills, you learn the value of discipline and see the rewards you get from your efforts. Like a lotus flower, your skills will expand outward from a center of strength and confidence. Do not envy those who seem to be naturally gifted; it is often a curse, as such types rarely learn the value of diligence and focus, and they pay for this later in life. This strategy applies as well to any setbacks and difficulties we may experience. In such moments, it is generally wise to stick to the few things we know and do well, and to reestablish our confidence.
