深度：俄为何想邀请中国访问国际空间站

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

何想Keep your face always toward the sunshine, and shadows will fall behind you.邀请Your limitation—it’s only your imagination.

中国站Your limitation—it’s only your imagination.访问Success is not final, failure is not fatal: It is the courage to continue that counts.国际Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

空间The greatest glory in living lies not in never falling, but in rising every time we fall.深度The way to get started is to quit talking and begin doing.

何想The only way to do great work is to love what you do.

邀请Don't wait. The time will never be just right.中国站It’s going to be hard, but hard does not mean impossible.

访问Wake up with determination. Go to bed with satisfaction.国际It’s going to be hard, but hard does not mean impossible.

空间Your limitation—it’s only your imagination.深度Great things never come from comfort zones.
