I can succeed
I have a dream,I can succeed.To have a great achievement in future and become the most successful woman.I believed,so long as I diligently.Why am I quite confident?Because I believe my ability and willpower will let me become an excellent person.
I have ever heard a well-known saying:"Catch the star that holds your destiny,the one that forever twinkles within your heart.Take advantage of precious opportunities while they still sparkle before you.Always believe that your ultimate goal is attainable as long as you commit yourself to it."
Suddenly,I found out I must never give up if I 'd like to achieve my goal!Though barriers may sometimes stand in the way of my dreams,I'll remember that my destiny is hiding behind them.The greatest gifts in life are not purchased,but acquired through hard work and determination.
It's difficult for us to succeed,but all of us can do anything perfectly on the premise that we should try our best and insist on our goal to make progress!At last,we can succeed!
I still believe I can do it!I will do it!I will succeed!And now I am standing on this stage,and I believe I can make it!
