OK - I just posted a few minutes ago, however, I came across this great article that I think everyone who teaches, sells, or markets anything should read. In fact, I would call it a must read. If its new to you - great! If it simply confirms a suspicion - pat yourself on the back. If you've been working this way for ages and ages now - you might consider teaching us a seminar.
So...after you have read the previous post...you should most definitely read today's thought from marketer and liar Seth Godin.
