Once you determine the area of study that interests you, you can become an authority in that field. Of course, it will take a lot of work, years of time, and loads of dedication in order to reach that goal, but you can do it if that's what you truly desire. Once you become an authority, it's important that you take the lead in modernizing and updating your area of expertise, in order to ready the field for the future.
This is one placement that won't let you throw the baby out with the bath water, so to speak; you're keenly aware of the necessity of using yesterday to prepare for tomorrow. If this important step is overlooked, you can easily become entrenched in your thinking, deadlocked in hopeless disagreement, stubbornly clinging to what you've been taught -- unteachable and unreachable. Try to avoid building up a wall in your mind; don't exclude new ideas simply because they don't easily incorporate into what you already know. Make it a point to remain intellectually flexible.
