The New York Times has a piece about a restaurant owner who turned his business around chiefly by giving himself a hard look in the mirror. It's a nice story and they use it to illustrate what they believe is a key business point which can apply to all of us:
In interviews we did with high achievers for a book, we expected to hear that talent, persistence, dedication and luck played crucial roles in their success. Surprisingly, however, self-awareness played an equally strong role.
I've read as many pieces about aiming high as you have so it's nice to have one that says there's value in stopping to look at yourself as you really are right now.
Read the whole piece including what happened with that restaurant and while you're at it, do please give Lifehacker a nod for spotting it.
