Why in Richards document view can still not have it all what in particular does he mean by it all and what evidence does he provide to support his position?

Richard's argument in "Document View: Why You Still Can't Have It All" is that people cannot simultaneously have a successful career and a fulfilling personal life due to the inherent trade-offs and sacrifices each choice requires. He provides evidence such as the long work hours and demands of modern workplaces, the pressure to Excel in one's career, and the challenges of maintaining relationships and family commitments. Richard argues that attempting to have "it all" can lead to burnout, stress, and unhappiness.
