@senradavid: Michael Dell explains why fear never goes away and why that's the point: " You don't want to fail, although failing is how you learn. Pain is the best teacher." "You can't have it paralyze you where you don't want to make any decisions because you're afraid to fail." "What you want to do is sort of be incremental. It's back to iterating. 'Okay, we are not sure if this is a good idea — let's try it. Let's experiment, let's get started, we'll figure it out.'" "We're not betting the whole company on this decision. We're just experimenting." " And if it doesn't work — great. We learn something. We move on."
