“Being powerful is like being a lady. If you have to tell people you are, you aren’t.” -Margaret Thatcher
If you have to tell people what a great person you are, what a big heart you have, how talented you are, how individual you are, or what a great sense of humor you possess, you likely have none of those things. Not to say you need to denigrate yourself, but seriously- be who you are. Unless you're a self important cow.
