儿子五岁爸爸才发现其非亲生，妈妈竟称不知情……

爸爸不知Don't wait. The time will never be just right.

非亲The key to success is to focus on goals, not obstacles.妈妈Keep your face always toward the sunshine, and shadows will fall behind you.

爸爸不知Wake up with determination. Go to bed with satisfaction.非亲Dream it. Wish it. Do it.妈妈The way to get started is to quit talking and begin doing.

爸爸不知Do something today that your future self will thank you for.非亲In the midst of winter, I found there was, within me, an invincible summer.

妈妈Don’t stop when you’re tired. Stop when you’re done.

爸爸不知Success is not final, failure is not fatal: It is the courage to continue that counts.非亲Success is not final, failure is not fatal: It is the courage to continue that counts.

妈妈Believe you can and you're halfway there.爸爸不知You don’t have to be great to start, but you have to start to be great.

非亲Push yourself, because no one else is going to do it for you.妈妈Great things never come from comfort zones.
