Hey, I'm like that too Barb! If something excites me I want to learn all about it...right now! I'll immerse myself in whatever it is and yes, sometimes that's a pain to those around me who may not be as excited about it as I am. The Montessori learning style says that this is how people learn, they immerse themselves in something and then move on as they master it or something else grabs their attention. It's much better than being someone who just doesn't get excited about anything!
