We learn English from babbling and read it. We are full of enthusiasm and have many talents. We become gentle from all the training. The whole process is an aging process, a fearless and indifferent process, and a bustling and back-and-forth process. When we were young, we could afford it but couldn't let it go. After twenty or thirty years of hard work, we have learned to let go. If you can put anything down, you won't waste a walk in the world. When we were young, we were competitive, showing off and cheering for our youth. After years of polishing, we have deposited a steady instrument, being humble and low-key. If you have a hidden attitude towards life, then you have not wasted a trip in the world. When we were young, we were passionate and ambitious, and lost our minds between gains and losses. After several ups and downs, we are not happy with things, but sad with ourselves. If you can concentrate on your own practice, you won't waste a walk in the world. None of the above is for fame and fortune. Say an elegant word: when you look back on the past, you will not be ashamed of mediocrity or regret wasting your time; A little more vulgar, I think of a sentence that Bai said before he died in "Da Zhai Men": In this life, I have enjoyed happiness and committed crimes. Bai was such a jerk when he was young and so generous when he died. This is not a waste of life. Life in this world, each has its own fate, cherish fate and accept blessings. If you live up to your heart, you will live a wonderful life and won't waste time in the world.
