what is luck

what is luck
My middle school life is going on.Now all of us are busy getting ready for the examination .After class,you can''t see any students go out of the classroom.They are busy studying at lunch time,most students usually have a quick meal,then go to the classroom quickly; on weekends,we can''t watch TV because we have much homework to do.Every day we are very busy and we feel very tired.
I really want some free time to enjoy myself when I am tired with my courses.
As a middle school student,I think grades are important,and also,interests are important.and i think it would be luck for us to have free time to develop our abilities in different fields.
