This means that no one who you consider a friend should be pressuring you to stay quiet or not let you grow, which means not allowing you to learn and develop as a person. A friend should never try to limit the things you can do, or stop you from growing. They should always be supportive and encouraging so you can continue to reach for your goals and be the best person you can be. People who suppress you in this way are not true friends and should not be in your life.
