As a cancer survivor I talk frequently on the topic of turning stumbling blocks into building blocks. I have become a master re-builder of taking the debris life throws in your way and creating something new and worthwhile.
One of my first lessons -- learned when I was quite young -- was the importance of having strong self-esteem and valuing your self worth. Whatever happens in life, these need to be a firm foundation for believing in yourself and your potential. This is something we must teach our sons and daughters.
