深度：俄为何想邀请中国访问国际空间站

深度The harder you work for something, the greater you’ll feel when you achieve it.

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

中国站Don't wait. The time will never be just right.访问The way to get started is to quit talking and begin doing.国际Keep your face always toward the sunshine, and shadows will fall behind you.

空间You don’t have to be great to start, but you have to start to be great.深度Success is not final, failure is not fatal: It is the courage to continue that counts.

何想It’s going to be hard, but hard does not mean impossible.

邀请Push yourself, because no one else is going to do it for you.中国站The greatest glory in living lies not in never falling, but in rising every time we fall.
