Who are you trying to please?
What are you promising?
How much money are you trying to make?
How much freedom are you willing to trade for opportunity?
What are you trying to change?

Having said all this, I highly recommend that you download his free e-book What Matters Now which is a collection of thought-provoking pieces by an impressive list of big-thinkers including: bestselling authors Elizabeth Gilbert and Daniel Pink,
Of course you can also read Seth's blog post announcing the availability of the book as well. It is a great free New Year's gift to yourself. Take a minute and download it. You will not be disappointed.
