Architect Frank Lloyd Wright used to cajole his architect students with this quip.
He meant that he was constantly working ideas out in his head and the process of drafting, of drawing, wasn’t creative, it was just the point at which he put his ideas down on paper.
You’re always thinking. Media such as pen and paper, Post-it® Notes, blogs, and recordings help thinking along. If you wake up in the middle of the night bursting with ideas, get out of bed and write them down. Welcome associations from every aspect of life. Mash-up your experiences against software systems expectations and create a new line of thought.
Your presentation and demonstration preparation are idea capture and articulation.
Shake those solutions out of your sleeves.
