There are 3 kinds of happiness. 1. Material Happiness 2. Hobby Happiness and 3. Spiritual Happiness. Material happiness can easily achieve with drinks, tobacco, and coffee. Too often those material become an unhealthy addiction. We can't feel peace without those chemicals. Hobby happiness coming from skills we develop over our lifetime such as painting, music or flower arrangement. Finally, when we identify we are not just ourself but the entire community and begin selfless giving and serving. For those who tasted spiritual happiness, they will never want to go back for the material happiness anymore. Once you can eat at a 5 stars restarnat, you will never want to go back to McDonald.
