A good life is having inner peace, where a person can do what they want to do (not what others pressure them to do, consciously or subconsciously). They need to have a purpose, goal or ambition in life.
To get to this stage, a person needs to practice saying how they feel honestly and openly even if it does inconvenience other people a bit, or feel uncomfortable to the person. They need to choose their friends carefully - be around those who lift them up, not drag them down. They need to remember what’s important to them and keep going until they achieve what they want to achieve.
