I get bored with what is already known after assimilating and understanding it.
I crave exploring the unknown, the as yet undiscovered and seek it out in the abstraction of random creativity.
It seems to me most people are primarily occupied with what is known and are fearful of the unknown in every aspect of their lives. They crave the routine of sameness and the known.
That area of focus is where human culture thrives, it is the fabric of trade, politics, civilization and survival. But without those of us poking our heads into the unknown, that survival would be jeopardized.
