Pondering over where our thoughts actually come from. A lot must have been said, examined, researched, assumed over that. Sometimes I think that the entire thought cycle is like a growing plant. It starts with a seed, the thinker keeps watering it with some more thoughts, things happen or circumstances solidify that thought (soil), someone smart sheds some light on it (photosynthesis :P)..the thought grows, gets rooted.. Till it gets uprooted, or it just might keep flowering.

Jeez. I just linked thoughts to gardening did i?
