What should come will always come. Don't worry about losing, greet hope with dawn and friendship. Which country and which poet wrote this handwritten poem?

I have never seen this poem before. You can Baidu, so it is inconvenient for me to copy and paste Baidu on my mobile phone. But there is a similar meaning. Tagore wrote in India: Don't be sad, don't be impatient, the melancholy days will pass, and the happy days will come ... I'm sorry if I can't help you.
