People who dare not try anything are doomed to be poor for a lifetime. It is safest for a car to be parked at home, but that is not the purpose of buying a car. As for people, lying in bed is the most comfortable, but that is not the meaning of life. As the old saying goes, if you want to be rich, you need to do business to open a shop and travel everywhere. People want to make troubles, and horses want to eat. A thousand suns shine on the boat, and it takes one day to cross the river. The road is walked by people, and things are done by people.
