"Hey, listen up guys! This is the time to be at our best, try our hardest to achieve our goals! We can't do that with such negative thoughts in our heads telling us that we can't do it! If we try our hardest, we can achieve almost anything! Don't listen to those negative comments they tell you, what'd they know?! You are your own person and no one is perfect! There is room for improvement just so long as you are willing to improve!
Keep true to your dreams, though; don't let them tell you that you can't one day be a famous movie star or a world acknowledged artist or author, you can do it as long as you set your mind on achieving that dream!
