I remember an old interview with the photoshop guru Kai Krause. He was sharing all his knowledge in a series called Kai’s Power Tips. And he was asked why he shared all his knowledge. “You’re giving away your best asset”. He answered that he wasn’t. He was giving away yesterday’s knowledge. He was already working on something new. (And what’s he doing now? Living and working in a 1000 year old castle. With a priceless view and lots of space.)
