Same stupid mentatality that some people have when they get behind the wheel of their car. Driving around over the speed limit in built up areas to save a minute or maybe two. They don't think about the increased risk of having an accident or running over a child.
Sunny, just operate at a pace that you are happy with. If not just do what I do, loose my mind, get out of the cockpit and say, right your the expert get in here and you fly this thing and I'll go home. Old age has made me very intolerant of fast pace people.
