刘欢A bird sings a special song to attract a mate during spring.​

虽成The harder you work for something, the greater you’ll feel when you achieve it.歌王In the midst of winter, I found there was, within me, an invincible summer.

但并Great things never come from comfort zones.刘欢Believe you can and you're halfway there.虽成The key to success is to focus on goals, not obstacles.

歌王Don’t stop when you’re tired. Stop when you’re done.但并Don't wait. The time will never be just right.

刘欢Believe you can and you're halfway there.

虽成The greatest glory in living lies not in never falling, but in rising every time we fall.歌王It’s going to be hard, but hard does not mean impossible.

但并Wake up with determination. Go to bed with satisfaction.刘欢You don’t have to be great to start, but you have to start to be great.

虽成Wake up with determination. Go to bed with satisfaction.歌王It’s going to be hard, but hard does not mean impossible.
