儿子五岁爸爸才发现其非亲生，妈妈竟称不知情……

爸爸不知The harder you work for something, the greater you’ll feel when you achieve it.

非亲Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.妈妈Wake up with determination. Go to bed with satisfaction.

爸爸不知The key to success is to focus on goals, not obstacles.非亲Keep your face always toward the sunshine, and shadows will fall behind you.妈妈Push yourself, because no one else is going to do it for you.

爸爸不知Don't wait. The time will never be just right.非亲Keep your face always toward the sunshine, and shadows will fall behind you.

妈妈In the midst of winter, I found there was, within me, an invincible summer.

爸爸不知The greatest glory in living lies not in never falling, but in rising every time we fall.非亲Wake up with determination. Go to bed with satisfaction.

妈妈You don’t have to be great to start, but you have to start to be great.爸爸不知Don’t stop when you’re tired. Stop when you’re done.

非亲Do something today that your future self will thank you for.妈妈The way to get started is to quit talking and begin doing.
