Changed the destiny
Although our fate (destiny) is doomed of god, we still can change it. We can remedy our defect if we were great effort enough. For example: The famous musician-- Kevin Kern who was blind by birth, and he has to rely on the sense of touch and feeling to know the world. He also has to learn music theory by Braille and search for the keys by feeling. He supports stern hinder and strike when he learns. He finally becomes a famous musician after a hard temper. He ever said, "trust yourself and the trust is existence of boundless". He not only achieves his dream but also bring this dream to everyone.
From this classical speech we can know, there are limitless colors and hopes full of the life. If people have hopes, it will be more sanguine about living manner and to be finding out solve ways when it had troubles, it also to do something won't give up. We can discover people have more confidence and constructive than other. We don't know what will be happening or meeting somebody in the future and maybe there is the most hope of the future, it will be next today. People often shut hopes in the box, if we don't open it, we won't see hope in the future. However, hope is the source of power.
