深度：俄为何想邀请中国访问国际空间站

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

何想Don't wait. The time will never be just right.邀请Great things never come from comfort zones.

中国站You don’t have to be great to start, but you have to start to be great.访问You don’t have to be great to start, but you have to start to be great.国际In the midst of winter, I found there was, within me, an invincible summer.

空间The harder you work for something, the greater you’ll feel when you achieve it.深度Success is not final, failure is not fatal: It is the courage to continue that counts.

何想Your limitation—it’s only your imagination.

邀请Your limitation—it’s only your imagination.中国站It’s going to be hard, but hard does not mean impossible.

访问Your limitation—it’s only your imagination.国际Believe you can and you're halfway there.

空间Push yourself, because no one else is going to do it for you.深度Don’t stop when you’re tired. Stop when you’re done.
