When I was a young child my mom would caution me about saying I can't do something.
It was funny, she had a little saying,
Can't couldn't do it and Could did it all.
This saying has undoubtedly shaped my self esteem.
Perhaps I have learned to be over confident in areas that I'm inexperienced in but that little nudge of "you can do it" has provided miles of usefulness in my life and career.
