Someone who has a strong will内心强大的人

 

They don't believe things will always go thevway you expect.

 

他们不相信生活总能尽如人意

 

If you're a pessimist, you should stop expecting storms. If you're an optimist, you should stop assuming there will never be clouds in the sky.

 

Always be prepared for the inevitability that our days can be very unexpected, either for good or for ill.
