In today's society people have much more opportunities to choose their jobs than ever.
Some of them tend to change their jobs from time to time.They think that it is a way in which they can get to know more of the world,make more friends and lead more challengging but colorful life.
However,some people still stick to only one job for a long time and do all they are worth to achieve their goals in those fields!
I prefer to specialize in one job and do it heart and soul.Only in this way will we accomplish the goal we set and be the best!
