The first Lean Startup meetup nn London was in 2009. It was full of founders who'd been burned, who had battle scars, had lost their time and money on their startups.

We didn't regret our failed startups because the experience was valuable, but we recognised the high cost we paid. We all had "I wish I knew that sooner" stories.

Sooner - is the key word here. Our job as founders is to bring ourselves the bad news sooner.
