Avoiding premature articulation just another way of stating one of the fundamental precepts of Creativity ‘Cycle Often and Close Late’. Why is this a good idea?
Have you ever rushed to complete an assignment, project or proposal just to get it out of the way, even though the actual deadline is a week or more away? Come the deadline you are aware of new material that you could have included to make it better or perhaps you realised that the grammar was less than perfect?
By all means get the work done but resist the option to ‘close’. You might deliberately revisit your work or just let the creative side of your brain work away on its own but stand firm. If you have many projects on the go then you might have to be good at time management and learn to live with a little ambiguity.
The results might be worth it though, your proposals will contain the latest information and your problem solving initiatives will have thoroughly explored all of the possibilities.
Premature Articulation is a condition that can be cured in all cases!
