What's your favorite sentence? How to understand it?

I like a poem by Wang Guozhen very much-

There is no mountain higher than man, and there is no road longer than man.

This sentence tells us

This sentence tells us that no matter how long the road is, as long as we keep going, we will always reach our destination. No matter how high the mountain is, as long as we climb it, we can be higher than it. In our daily life, study and work, we will always encounter many difficulties, which cannot be met at once. Persistence in doing things, persistence is victory! As long as we stick to our inner beliefs and keep working hard, we can conquer the highest mountain and do the most difficult things well.
