Excerpt from President Obama’s National Address to America’s Schoolchildren (2009) Now, I know it’s not always easy to do well in school. I know a lot of you have challenges in your lives right now that can make it hard to focus on your schoolwork. I get it. I know what it’s like. My father left my family when I was two years old, and I was raised by a single mom who had to work and who struggled at times to pay the bills and wasn’t always able to give us the things that other kids had. There were times when I missed having a father in my life. There were times when I was lonely and I felt like I didn’t fit in. So I wasn’t always as focused as I should have been on school, and I did some things I’m not proud of, and I got in more trouble than I should have. And my life could have easily taken a turn for the worse.
