Ah, finally an answer to my strange childhood habits.
I was the kid that would run up and down in a perfect line, shaking the hands rapidly, and making funny faces for hours on end. My parents worried for me, but I assured them that I needed this to get absolute potential out of my day-dreaming. I created worlds; magnificent and elaborate universes of lore, stories and legends. I got my inspiration from anything and everything, like dreams, books, movies and even a sun-set. As I became older, I tamed my behaviour down quite a bit, balancing it with my life and treating it as a "do all the time your not doing anything important" thing. It has sparkled my creativity, and I have a non-stop machine for my writing hobby and art. In fact, if it wasn't for this little "disorder" I wouldn't have the plot-line for my current novel up and running.
There is a balance. Sometimes it is painful to know that what you create isn't real, but other times there is a sweet bliss that you have the imagination there. Certain things that you create in your mind can become reality in the form of ideas and inventions, goals and purposes. I myself hope to graduate from high-school and head right into my line-up to become a scientist. You never know what can happen in this world, and I plan on succeeding in my visions with my intuition and wandering mind.
Gosh, I sure am glad to see that there are others out there who behaved peculiarly as children though. I thought I was the only pacing-child with the funny faces and fantasy land. Guess not :P
