Letter to Bill Clinton
When I walked into this office just now I felt the same sense of wonder and respect that I felt four years ago. I know you will feel that, too.
I wish you great happiness here. I never felt the loneliness some Presidents have described.
There will be very tough times, made even more difficult by criticism you may not think is fair. I'm not a very good one to give advice; but just don't let the critics discourage you or push you off course.
You will be our President when you read this note. I wish you well. I wish your family well.
Your success is now our country's success. I am rooting for you.
