Epicureanism is a kind of philosophy that focuses on having a happy life. It was developed by a thinker named Epicurus in ancient Greece. The basic idea is that we should enjoy life's pleasures and avoid any pain or suffering. It also encourages us to be content with what we have and stop striving for more. Epicureans focus on having a simple and enjoyable life, free from fear and worry. They believe that a little bit of pleasure is better than a lot of pain, so they prefer to take part in activities that will bring them joy. They also believe that thinking too much about the future can bring stress and worry, so they try to focus on the present moment.
