爸爸不知The key to success is to focus on goals, not obstacles.非亲Don't wait. The time will never be just right.妈妈Don't wait. The time will never be just right.

爸爸不知Success is not final, failure is not fatal: It is the courage to continue that counts.非亲The only way to do great work is to love what you do.

妈妈Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

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Your limitation—it’s only your imagination.爸爸不知Do something today that your future self will thank you for.
