My strength is as the strength of ten,
Because my heart is pure.
—Lord Alfred Tennyson

My mother shared the last two lines with me when I was a teenager. I was going through some tough times as I was trying to straighten out my life. As I did so, I was struggling with the backlash I got from what turned out to be false friends. That quote really struck a chord and gave me strength when I greatly needed it. I've never forgotten that quote and have oft remembered it when I needed courage.
