I wrote this book to tell my story, and to tell the story of America in the last half of the twentieth century; to describe as fairly as I could the forces competing for the countrys heart and mind; to explain the challenges of the new world in which we live and how I believe our government and our citizens should respond to them; and to give people who have never been involved in public life a sense of what it is like to hold office, and especially what it is like to be President.

While writing, I found myself falling back in time, reliving events as I recounted them, feeling as I did then and writing as I felt. During my second term, as the partisan battles I tried to defuse continued unabated, I also tried to understand how my time in office fit into the stream of American history.

That history is largely the story of our efforts to honor our founders charge to form a more perfect union. In calmer times, our country has been well served by our two-party system, with progressives and conservatives debating what to change and what to preserve. But when change is forced upon us by events, we are all tested, and thrown back to our fundamental mission to widen the circle of opportunity, deepen the meaning of freedom, and strengthen the bonds of our community. To me, that is what it means to make our union more perfect.

At every turning point, we have chosen union over division: in the early days of the Republic, by building a national economic and legal system; during the Civil War, by preserving the Union and ending slavery; in the early twentieth century, as we moved from an agricultural to an industrial society, by making our government stronger to preserve competition, promote basic safeguards for labor, provide for the poor, the elderly, and the infirm, and protect our natural resources from plunder; and in the sixties and seventies, by advancing civil rights and womens rights. In each instance, while we were engaged in the struggle to define, defend, and expand our union, powerful conservative forces resisted, and as long as the outcome was in doubt, the political and personal conflicts were intense.

In 1993, when I took office, we were facing another historic challenge to the Union, as we moved from the industrial age into the global information age. The American people were faced with big changes in the way they lived and worked, and with big questions to be answered: Would we choose global economic engagement or economic nationalism? Would we use our unrivaled military, political, and economic power to spread the benefits and confront the emerging threats of the interdependent world or become Fortress America? Would we abandon our industrial-age government, with its commitments to equal opportunity and social justice, or reform it so as to retain its achievements while giving people the tools to succeed in the new era? Would our increasing racial and religious diversity fracture or strengthen our national community?

As President, I tried to answer these questions in a way that kept moving us toward a more perfect union, lifting peoples vision, and bringing them together to build a new vital center for American politics in the twenty-first century. Two-thirds of our citizens supported my general approach, but on the controversial cultural questions and on the always appealing tax cuts, the electorate was more closely divided. With the outcome in doubt, bitter partisan and personal attacks raged, bearing a striking resemblance to those of the early Republic.

Whether my historical analysis is right or not, I judge my presidency primarily in terms of its impact on peoples lives. That is how I kept score: all the millions of people with new jobs, new homes, and college aid; the kids with health insurance and after-school programs; the people who left welfare for work; the families helped by the family leave law; the people living in safer neighborhoodsall those people have stories, and theyre better ones now. Life got better for all Americans because the air and water were cleaner and more of our natural heritage was preserved. And we brought more hope for peace, freedom, security, and prosperity to people all over the world. They have their stories, too.

When I became President, America was sailing into uncharted waters, into a world full of apparently disconnected positive and negative forces. Because I had spent a lifetime trying to bring together my own parallel lives and had been raised to value all people, and, as governor, had seen both the bright and dark sides of globalization, I felt I understood where my country was and how we needed to move into the new century. I knew how to put things together, and how hard it would be to do.
