The old saying "The early bird catches the worm" show us the importance of planning,working hard and trying constant.To achieve outstanding results,the most people must plan ahead and work diligently to overcome all kind of difficulties.
That has been my own experience,either.When I first started at high school,I seldom passed my exams,so I never prepared well.Later,my teacher,Mr.Black,advised me plan everything in advance.She asked me to study hard as well.After a year of putting his advice onto practice,I can now easily pass all my exams.
There are no shortcuts to succeed.
