Q: In terms of brain function, explain the difference between "simple" and "easy or difficult."
A: The task is a bit daunting, at best, since every human brain on this planet is unique. No two brains are believed to be identical in structure, function, or perception; and each will perceive information against the backdrop of its own experience, ability, bias, education, and belief systems to name just a few.
Think of it this way, the goal of eating moderate amounts of nutritious food at regular intervals is a simple concept. Is it always "easy" for people to achieve when they are bombarded with multi-media presentations, societal pressure to eat, and memories of learned behaviors? No.
Similarly the concept of living life tobacco free is relatively simple. "Yes or no." Altering behaviors related to tobacco use, however, is not necessarily easy and actually may be one of the most difficult behaviors to change.
And the goal of obtaining regular physical exercise is also a relatively simple concept. You do it or you don't. But how many people obtain at least 30 minutes of balanced exercise on a daily basis?
These tasks are "simple," and yet not necessarily "easy" to accomplish. They require vision, focus, commitment, choice, and discipline, along with setting and implementing appropriate personal boundaries, and so on. This can make them "difficult" to implement. In most cases, however, it is probably worth the work depending on your own goals.
In terms of brain function, the concept of figuring out how your brain functions most energy-efficiently is relatively simply. So is developing the goal of matching a minimum of 51% of your life's activities to that innate giftedness is relatively simply to understand.
Applying that knowledge and implementing steps to achieve that goal (while simple in concept) may be easier or more difficult to accomplish. It can be easier when you have not been Falsifying Type (a label coined by Jung to indicate that an individual has built more than half their skills outside their innate brain lead); and when your business associates, friends, and family members are willing not only to honor who you are innately but to support and affirm you as you tweak your life's activities to attain that 51% match.
This process can be much more difficult when you have been adapting for years, your brain is already exhausted and your immune system stressed; and when your business associates, friends, or family members believe it is their best interests for you to keep functioning in the same style. They may even make it uncomfortable for you to live the way in which life is energy-efficiently for your brain.
Of course one could argue that if they really cared about you, "Joe Blow," or "Jane Smart," they would get behind this process because of the huge benefit that can accrue to you in terms of health, wellness, success, and longevity. Hope springs eternal!
Regardless, anecdotal information over time is supporting the belief of how important it is for an individual to follow their own path-regardless. Simple in theory. Practically it usually requires a mix of easy and difficult to achieve. We believe it is definitely worth the work!
