Human beings have wisdom. That's something you and another can share together. Have a conversation, not a confrontation. Get other people interested in hearing you and your ideas. Negative speech will make you a negative person.
Happy people are healthy, optimistic, and have more driving force to achieve.
That's mere survival. Happiness is in your control. By not controlling it, you are slave to your emotions. Happiness requires discipline, determination and hard work. Don't wait for it to happen.
