What traits do you associate with which numbers?
It can be anything at all.
I'll start off with mine.
1 - Number of genesis, origin, existence. No movement, only presence.
2 - Number of process and continuation; desire to move continuously onwards. Once Two has been reached, the upward progression must continue.
3 - Number of disgruntlement, complacency, and reality. Has little energy of its own; represents uneven properties; things in one's surroundings that simply exist but adhere to no apparent system or harmony.
4 - Number of completion, negation, void. Perfect number, perfect symmetry, a cancelling of all opposing forces; a state of perfect rest. Completion of the cycle.
5 - Number of rebellion, impulse, irrationality. Break from the state of perfection instilled by Four. Deliberate, willful displays of disorder.
6 - Number of technology; unites the state of Nature (Three) with states of progression, logic, and negation of opposing forces (Two).
8 - Number of imitation, redundancy, and mockery. Lacks any substance of its own; void; product created by doubled states of "perfection" cancelling out each other to no effect.
