Another aspect of decision-making is timeframe; I keep decisions close to me and don't get too far ahead.  I don't trust myself to know what I'll want in the future, and fear getting trapped in something that's lost its appeal.  I live more reactively, making decisions when they're in front of me, more or less.

In art as in life:  My work is a process of immediate decisions that responds to what's actually there without a fixed (or any) vision of what will come of it.  I may end up with rubble but it's the only way I end up with work that surprises me.  The work takes the lead; I listen and follow.
