Lots of people have ideas.  Very few people act on them.  Between having an idea and shipping it is the real work, the execution.
Without the ability to execute an idea is just that, an idea.
Zuckerberg had something the Winklevi did not, the ability to execute, quickly.
The magic is in the execution.

I keep a sign above my desk as a reminder of this. It’s big and it says “Stop Talking. Start Doing.”
Good words to live by 
Thanks,
Thanks, this put things in perspective for me at a perfect time.

I often tell people: “Conception and execution are two totally different things.” Its a very good point and one that is easily overlooked.
Leaders activate and execute their ideas. Executing is the key to accomplishing great things. Thank you for the post.
