Stop carrying the weight of the world on your shoulders.
别太操心了,没有你地球照样转。 (carry the weight of the world on one’s shoulders:自以为重任在肩。)
I always carry matches with me at such times and I tore out the pages of the first chapter of the book I was reading to get the fire going.
在这样的时候我身上总是带着火柴的,为了让火堆燃下去,我从我正在看的那本书的第一章撕下几页。
