One of the golden nuggets that has stuck with me over the years came from good friend David Heath when we were both at Apple UK.
"Remember Paul, it's always easier to ask for forgiveness than to ask for permission"
This week I was reminded of the phrase in as slightly different context
If You Want To Achieve Greatness Stop Asking For Permission.
Stop asking your bosses for permission to implement that new strategy that you know will bring in hundreds of new customers, they won’t give it to you, just take matters into your own hands. And stop asking your friends to leave you alone for just a bit so you can focus on your passion, they try to but they won’t leave you alone, just leave and focus on your work (and explain later).
