How to be confident: See your strengths, not your weaknesses.
"I really wanted children, but I couldn't conceive. For a while I hated my body for not doing the one thing it was designed to do, and I punished it at the gym. I figured that if I couldn't have a baby, at least I could be skinny! Then a friend suggested I go hiking with her. Before I knew it, I stopped being so critical—I was too focused on the hills, colors, and sky to worry about my weight. I finally saw all that my body was capable of—which helped me love it again."
