I'd like to share my thoughts with you on this matter.
Yes, talent shows may change one's future. They give people a chance to show their talents, and give people a way to make their dreams come true. But I think there is no need to take the result too seriously. It may not be good for us teenagers to become famous overnight. So just enjoy the process.
There are many ways to succeed, and only by working hard can you make your dream come true.
As a teenager, you should study hard and develop your interests at the same time. I think you will succeed in the future.
