If you want to be at the top of the food chain, it pays to observe how nature's own big cats operate. Lions aren't chasing prey all the time. In fact, like their smaller brethren, they spend most of their time SLEEEPING and CHILLING OUT. So what's the lesson here? No it's not to slack off. I think the lesson is that you want to always keep a reserve ready, for when that juicy antelope crosses your path.
