Somebody just back of you while you are fishing is as bad as someone looking over your shoulder while you write a letter to your girl. Ernest Hemingway
Don't look over your shoulder and don't use or abuse others to get ahead. Keep your eyes focused on your goals and keep working for what you believe in and what you want to accomplish. Richie Sambora
It is a terrible thing to look over your shoulder when you are trying to lead -- and find no one there. Franklin D. Roosevelt
Life's greatest comfort is being able to look over your shoulder and see people worse off, waiting in line behind you. Chuck Palahniuk
The past can be a terrible weight bound to you by an unbreakable chain. You can drag it with you, forever looking over your shoulder at what holds you back. Or you can let it go and move forward. It's your choice. Raymond E. Feist
Close the door. Write with no one looking over your shoulder. Don't try to figure out what other people want to hear from you; figure out what you have to say. It's the one and only thing you have to offer. Barbara Kingsolver
