I prefer studying.Because whatever job you are doing,you can do nothing good without learning.If there is a chance to let me choose one for life,that should be studying.In my opinion,developing is fundamental for all kinds species.And you will fully recognize that it is all about learning and creating,and further,creating in strictly based on your knowledge that you have learnt.
I prefer team work.It can be easily found that one person can do little thing,however,group of people can make wonders come true.For an instance,a good translater can do translate a book but an encyclopedia by group of translaters in the same period of time.
