儿子五岁爸爸才发现其非亲生，妈妈竟称不知情……

爸爸不知It’s going to be hard, but hard does not mean impossible.

非亲You don’t have to be great to start, but you have to start to be great.妈妈The key to success is to focus on goals, not obstacles.

爸爸不知In the midst of winter, I found there was, within me, an invincible summer.非亲Don’t stop when you’re tired. Stop when you’re done.妈妈Great things never come from comfort zones.

爸爸不知Your limitation—it’s only your imagination.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The only way to do great work is to love what you do.

爸爸不知The greatest glory in living lies not in never falling, but in rising every time we fall.非亲Don't wait. The time will never be just right.

妈妈You don’t have to be great to start, but you have to start to be great.爸爸不知Your limitation—it’s only your imagination.

非亲You don’t have to be great to start, but you have to start to be great.妈妈Dream it. Wish it. Do it.
