Education and training are critical, as they are the second component to “doing the knowledge.” What is required is root knowledge, not merely branch knowledge. You cannot master a subject by making a cursory glance of it. To obtain a comprehensive knowledge requires digging deep, even if you are ahead of the game because of a natural aptitude for a particular subject. There is no such thing as too much knowledge. However, you can have too little, and a little knowledge is usually dangerous. That’s when you’re likely to take uncalculated risks and enter a minefield ill-equipped and unprepared.
After defining your goals and vision, you need to learn what is necessary to achieve it.
Take the time to study your chosen profession. Such knowledge can be obtained either in school or in life. Mentors and teachers come in to play here. They can provide you the information you need to move forward, especially in the beginning.
