The first youth is given by God; The second person's youth depends on his own efforts.

Since there are black spots on the sun, it is even more impossible for things in the world to be without defects. If people are optimistic, everything is resistant, everything can be resisted, and everything will enhance resistance. Optimists see opportunities in disasters; A pessimist sees disaster in every opportunity.

The wind blows the sky and waves attract you. Just smile and don't worry.
