Here is a quote from George Bernard Shaw
"People are always blaming their circumstances for what they are. I don't believe in circumstances. The people who get on in this world are the people who look for the circumstances they want and if they can't find them, make them"
This is a powerful quote - how often do we blame everything around us for not being "successful"?
I believe that we all make a difference, if we want to.....making it happen can be hard but that is what makes achievement feel so great. So if you are faced in your team with people who say "I can't because...." then ask them "How can we create the circumstances.... or What do we need to do to ensure success"
