This has a simple consequence: you must choose places of work and positions that offer the greatest possibilities for learning. 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. This means that you move toward challenges that will toughen and improve you, where you will get the most objective feedback on your performance and progress. You do not choose apprenticeships that seem easy and comfortable.
