Time and structure go hand in hand. I've been learning the hard way.
When the hours of my day are highly structured, I feel imprisoned, constrained, controlled. No space for the imagination to explore, no place for the unexpected to intrude, no room for conversation to deepen or the new to emerge.
I've been surprised to discover that the absence of structure isn't much better. No boundaries to all the possibilities. No deadlines around which to develop priorities. Infinite options available at every moment paralyze instead of empower. The mind bogged down with continually justifying the current use of time against all the others.
So I'm building structure into my day. Enough to focus efforts, prioritize decisions, and make actual progress. Not so much to shut down the creative spaces and interactions I need to function as well. Life, of course, is a learning process. I keep being surprised, though, by where the lessons turn up.
