Who can help me explain what this sentence means?

Literally, it is difficult for teenagers and their fate is bumpy. My brother's ancestral business is unreliable, but he can earn money but can't save it. Like cobwebs, the morning is a garden, and the afternoon is not round. If you fail several times, you can only keep your family business. Who knows, there will be another disaster. At the age of forty, I made a comeback and was in full swing. Gradually, the family business flourished. The wife can grow old together after the formula. The death of my son and daughter-in-law is a big hurdle. If I can get by, I will live to sixty-nine and die in autumn.
