It remembers me of another article, about producers and consumers: "The Single Most Important Career Question You Can Ask Yourself" http://www.softwarebyrob.com/2008/05/18/the-single-most-impo...

If you’ve been reading startup blogs for years and never started anything, it’s time to accept that your tendency is to be a consumer. It’s not to say you can’t break out of that classification by starting something, but if you haven’t done it thus far you’re not likely to do it soon without some external motivation (maybe this post?).

If you have 50 software product ideas and your hard drive is littered with folders containing 30 lines of code from each, you tend towards being a consumer (or at least a producer who has trouble finishing things).

And if you figure out that you are a producer, stop daydreaming about the day you’ll make things happen. Start making it happen in the next 30 days, or forever hold your peace.

Once again, is the ability to ship something the major distinction.
