"The paralysis of unlimited opportunity"from Seth's blog:
There aren't just a few options open to you, there are thousands (or more).
You can spend your marketing money in more ways than ever, live in more places while still working electronically, contact different people, launch different initiatives, hire different freelancers... You can post your ideas in dozens of ways, interact with millions of people, launch any sort of product or service without a permit or factory.
Too many choices.
If it's thrilling to imagine the wide open spaces, go for it.
If it's slowing you down and keeping you up at night, consider artificially limiting your choices. Don't get on planes. Don't do spec work. Don't work for jerks. Work on paper, not on film. Work on film, not on video. Don't work weekends.
Whatever rule you want...
But no matter what, don't do nothing.
