When people give a speech, everyone likes to wish people good luck. It is necessary and polite to extend good wishes to others. What if people do the opposite thing? you may surely think the person is selfish, but you are wrong. Recently, a father gave a speech at his son's ninth grade graduation ceremony. He began his speech with different words. He said he was not going to wish people good luck and explained it. He wished the young people to meet setbacks and then became strong persons. People gave warm applause to his speech. Indeed, no one will be lucky all the time. Life is unfair and we need to adjust it. Everyone needs to learn that nothing comes easy and cherish what they have. So don't take the things you have as granted and be grateful for life.
