As human beings, we are all born free. However, as time passes, we all feel constrained, unable to live our lives as we choose. This is why, as individuals, we are always seeking freedom—freedom to follow our passion, freedom to travel the world anytime, freedom to decide when to retire, and freedom to live the life we have always imagined. But as they say, there is no such thing as a free lunch. Everything, including our freedom, has a cost.
