Every drink or shareable is only $6.00! **Happy Hour** is inherently social. It’s a time when people come together to unwind and enjoy each other’s company. For many, it’s a way to catch up with friends, network with colleagues, or simply meet new people in a relaxed setting. The casual atmosphere of happy hour encourages conversation, making it easier to bond over shared interests and experiences.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!
