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Believe you can and you're halfway there.

爸爸不知It’s going to be hard, but hard does not mean impossible.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Keep your face always toward the sunshine, and shadows will fall behind you.非亲The key to success is to focus on goals, not obstacles.

妈妈The way to get started is to quit talking and begin doing.

爸爸不知You don’t have to be great to start, but you have to start to be great.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Don’t stop when you’re tired. Stop when you’re done.爸爸不知Do something today that your future self will thank you for.

非亲The harder you work for something, the greater you’ll feel when you achieve it.妈妈Believe you can and you're halfway there.
