Being recently(~18mths) out of University and progressing in the early part of my career, I recently read "I could do anything if only i knew what it was" by Barbera Sher.
This link has a good summary of the main points of the book.
I discovered that I am most likely a scanner - defined as:
"Scanners want to taste everything. They love to learn about the structure of a flower, and they love to learn about the theory of music. And the adventures of travel. And the tangle of politics. To scanners, the universe is a treasure house full of a million works of art, and life is hardly long enough to see them all. "
This sounds like me. I find almost all things fascinating, and strive to acquire a substantial level of knowledge in a seemingly random array of subject matter. I will be obsessed with, say, medieval history, then upon learning plenty I become bored and move on to quantum physics or some such. Seems like a gift and a curse!
I once thought it was ADD or simply a lack of discipline but have since realised the attention level and the fixation on each topic area is exceptionally high - at least until interest levels wane.
Is there anyone else out there that might fit into this category? What kind of careers have you chosen? What is the best way to tie such natural abilities into a world which is (probably) more suited to the deep diving 'Specialists'?
