I am a woman. Please read it for me. I don't understand this text. Please explain and translate. Thank you.

Want to hear it? It is said that this life is hard, and there is no good luck in this life. All my efforts will be in vain. I am smart, clever, open-minded and ambitious. When I was young, I could study hard and get into a good university. Young and middle-aged people are short of money and unprofitable. I am polite, loyal, talented and diligent. It is not good to help others all your life, but it is not good. Friends and relatives are reliable. Only one of the three children can die. He died in the spring at the age of 77.
