Marc Andreessen, co-founder of Netscape and general partner of venture capital firm, Andreessen Horowitz, summarizes this notion very well in the following quote from a WSJ article:
“One of the things I always tell our entrepreneurs is, don’t just hire people out of successful companies, because the people out of successful companies didn’t learn anything. Maybe they were just along for the ride. Whereas, the people who have been through tough times tend to be much more resilient and they tend to be much more determined and they’re not daunted by things being hard.”
