牛人權(quán)威答題：
It has alwasy been a trade-off between labor and leisure.Some people do not believe in this and work their way out by trying to work leisurely.However,I still advocate that while doing work,one has to keep oneself in a stressful condition and get the momentum on.In my opinion,one should highly focus on one's job while working and then have fun and enjoy the leisure time after working.These two things cannot be mixed up together.Only by working stressfully can one yield the highest efficiency.Working leisurely will simultaneously make one lower the expectance of the work result.This will have significantly different output from working stressfully.To keep a stressful working can also make one enjoy life and keep a positive mood,since some pressure is actually good for people to enjoy the rest of time better.As the saying goes,"Work hard,play hard." I prefer to do my work in a rather stressful way.
