Give yourself a D – Seth Godin (Linchpin)
Failure happens. If it does, you’ve learned something.
I have always believed that writing advertisements is the second most profitable form of writing. The first, of course, is ransom notes . . . ~ Philip Dusenberry
Great spirits have always encountered violent opposition from mediocre minds – Albert Einstein

This may not seem to have a lot to do with marketing, but it does. If you only give and give you will be poor and hungry. It is OK to want to earn money for your work, and be paid accordingly. However, if you only interrupt people and act selfishly, you will be perceived as greedy and self-centered. Give some things away (but not everything). What are you waiting for? If it’s Godot, he’s not coming.
