2. A truly learned person is like your ear of wheat: as long as it is empty, stand up straight and look up; But when they are mature and full of swollen wheat grains, they bow their heads humbly and don't show their edge, so they abandon their pretentious psychology and admit their original position. -Montaigne
Sincere and rational friendship is priceless in life. Whether you can be faithful to your friend and always be a person worthy of him is the best test of your soul, personality, psychology and even morality. Marx
4. Stay optimistic. Love your life and work. Be good at finding fun in life, even if you do housework, don't take it as a burden, but do it with interest, constantly create in your work, realize your life value in progress, and constantly feel the joy of success. Be good at eliminating bad emotions. Don't hold back things that don't go your way, but be good at telling your troubles or puzzles in time.
